Instead of deleting and rebuilding #private-container every time its
contents need to be updated, just replace its contents. This
eliminates some scrollbar flashing.

This section was taking up too much visual weight, and drowning out other
elements on the page.
Once we remove the Upload buttons, we can likely shrink this further.
We remove the box-radius since at the smaller size it interferes with how
the logos look (and will look in the app).
We remove the margin-top to make this consistent with the spacing around
organization profile picture.
We change the max width from 730 to 500 since the Upload new logo button is
214px in length (not including margin), and those buttons are now inline
instead of on the next line.
This commit migrates the Subscription's notification fields from a
BooleanField to a NullBooleanField where a value of None means to
inherit the value from user's profile.
Also includes a migrations to set the corresponding settings to None
if they match the user profile's values. This migration helps us in
getting rid of the weird "Apply to all" widget that we offered on
subscription settings page.
The mobile apps can't handle None appearing as the stream-level
notification settings, so for backwards-compatibility we arrange to
only send True/False to the mobile apps by applying those defaults
server-side. We introduce a notification_settings_null value within a
client_capabilities structure that newer versions of the mobile apps
can use to request the new model.
This mobile compatibility code is pretty effectively tested by the
existing test_events tests for the subscriptions subsystem.
If MAX_FILE_UPLOAD_SIZE is set to 0, then UI elements like the upload
icon in the compose and message edit UI and "Attachments" menu in
"/#settings" are not displayed.
A different error message is also displayed if a user tries to drag and
drop or paste a file into the compose message box.
Fixes#12152.
All the elements to which `display-none` class
is applied, are handled with `.show()`/`.hide()`
functions instead of `.addClass('display-none')`
and `.removeClass('display-none')`.
Therefore, we should use apply `display: none;`
to elements with `style` attribute.
This commits removes all usage of `display-none`.
The css of `display-none` class was override by
`.rendered_markdown tr` class's css.
This commit fix this regression by applying style
to html element instead of class.
This adds three bools to message_container object which calculate bools
where the "(EDITED)" label should appear:
* `edited_in_left_col` -- when label appears in left column.
* `edited_alongside_sender` -- when label appears alongside sender info.
* `edited_status_msg` -- when label appears for a "/me" message.
We use the new bools and remove the complicated if else statements
from the templates for the "(EDITED)" label.
This also allows us to add a unit test to verify the logic.
Cleanup single message template moving CSS rules for box shadow
of a private message stream inside stylesheets. For any messagebox
inside of a `.private-message` element, the box shadow is set using
the class. In cases of normal streams, the box shadow is set using
inline style since we cannot have different classes for each color.
Changes made in drafts.scss are to keep the current style of not
having the left border. Setting style using classes, this rule had
to be overridden.
This commit renames the `create_stream_permission` field in the
templates to `create_stream_policy`, matching the field used in the
database model. This matches what `invite_to_stream_policy` does and
will be clearer when the `waiting_period_threshold` is split into its
own field.
Fixes#12251.
Previously when disabling name changes in server settings, instead
of realm settings, the name edit button did not get disabled.
Changing name resulted in a message stating `no changes made`.
Fixes#12132.
Realm setting to disable avatar changes is already present.
The `AVATAR_CHANGES_DISABLED` setting now follows the same
2-setting model as `NAME_CHANGES_DISABLED`.
This is useful when syncing avatars from an integrated LDAP/active
directory.
The upload avatar and delete avatar buttons are hidden if avatar
changes are disabled and the user is a non-admin.
If the user has a gravatar set, then the user will not be able to
upload an image as their avatar if avatar changes are disabled.
Part of #12132.
This commit creates a new organization setting that determines whether
a user can invite other users to streams. Previously this was linked
to the waiting period threshold, but this was both not documented and
overly limiting.
With significant tweaks by tabbott to change the database model to not
involve two threshhold fields, edit the tests, etc.
This requires follow-up work to make the create stream policy setting
work how this code implies it should.
Fixes#12042.
This bug turned out to pop up wherever a table existed in both
'settings' and 'organization settings', notably *excluding* both
'Custom Emoji' and 'Authentication Methods'.
The first thought to the solution was to simply add `thead` to the css
rule that applies the appropiate color for headers and the like. This
was successful, however it brought attention to a sub-problem:
`emoji-settings-admin` and `auth-mehtod-settings-admin` were both
creating table headers in the body of the table. This was causing the
rows in these two tables to be colored inversely from all the others.
This is also the reason why these tables are the only ones correctly
styled. These handlebars were updated with the headers moved out of the
body.
The even and odd rows of the tables were then colored appropriately.
Fixes: #12209
This commit adds a `insert_tip_box` function and thus adds a
`organization-settings-tip` handlebars file to add a genaralised tip for
all organization settings pages. This further removes the code for tipbox
which was added in `populate_auth_methods` functions, as it wasn't making
sense there, making it more clear and readable.
This commit adds a class prop-element for all the property elements, so
that later on we can directly use this to access elements.
In `get_subsection_property_elements`, we were finding these elements using
a makeshift method, where we were finding all these elements by mentioning
all input elements, textarea, select elements, which is not a desirable
method.
So now, here in `get_subsection_property_elements` function, we are finding
these properties using the newly added class `prop-element` which makes
code more clear and readable.
There are no other <h5>'s in static/templates. Basically just copied the
styling of `#settings_page h3` above it.
The vertical spacing here isn't great, but I think will require some deeper
fixes.
The order in the streams section is visual, audio, mobile, email, which also
seems to match other products (though didn't do a careful analysis). This
changes the PM section to match.
This reverts commit 6441ad0677 since it
causes two bugs: (1) when rendering new message there is glitch where
the profile picture flashes (2) when someone sends a new message their
profile picture flickers.
Now that we have a scroll container for the PM list,
it doesn't make much sense to limit the number to
five.
We may resurrect this feature if "more conversations"
actually fetches more conversations, but it doesn't
currently.
We also may soon make it easy to limit PMs to just
unread messages, which will make the max-5 feature
perhaps less necessary, and we don't want to make
the UI overly complicated.
This adds a class `rendered_markdown` for all the elements which have
rendered markdown content; This is done to add different styles for
rendered content in day mode and night mode.
Also replace the element selectors from CSS to use the class.
Using lazysizes we only load images if they are in view.
This decreases load time and save more bandwidth since images are loaded
after html is loaded and if they are on screen.
Fixes#3564.
This disables the Deactivate button for the current user in the Users tab,
so that it becomes hard to deactivae yourself accidently from Users tab.
Fixes#10427.
This renames references to user avatars, bot avatars, or organization
icons to profile pictures. The string in the UI are updated,
in addition to the help files, comments, and documentation. Actual
variable/function names, changelog entries, routes, and s3 buckets are
left as-is in order to avoid introducing bugs.
Fixes#11824.
We have this strange business requirement that the
blue-ish highlights for the current PM go into the
left gutter and all the way to the right edge.
We also have markup that treats the list of PMs
as a list inside the list item for the "Private
messages", which makes sense logically.
Before this change, the padding was done for the
outer top-left `ul`, but that caused the inner PM
rows not to have that padding when you hovered them.
Now we pad each individual list item and/or inner
list item or div.
Fixes#11879.
This moves the configuration of widget type from settings_org to instead
live in respective HTML templates, via `data-widget-setting-type` and we
also remove `get_subsection_property_types` and refactor function
`populate_data_for_request` accordingly.
Fixes: #11708.
This fixes several bugs with /me messages:
* We no longer hover name if you're over
the message.
* We now launch the user popup if you
click on the name.
* Even if you click on the avatar, we
launch the user popup to the right
of the name. (I think this is odd,
but it's consistent with how we
do it for normal messages.)
The underlying problem here is that you have
two possible organizations.
From a logical standpoint, the image and
name go together (and both launch the user menu):
img Alice | says hi
From a physical perspective, the main message
is "Alice says hi" and it's aligned differently
from the image:
img | Alice says hi
Our HTML reflects the latter.
HTML doesn't allow overlapping diffs, of course,
so you have to pick your poison.
One goal of this commit is to just make the "happy
path" code a lot easier to read. It should be
pretty easy to verify that in this diff.
And then more stuff is now in me_message.
This is a pure code move, and it doesn't fix these
structural issues yet:
* the "say hi" part of "/me says hi" is
inside ".message_sender" (due to legacy
positioning issues)
* the avatar is outside of .sender-status
(again due to legacy positioning issue)
* we don't have sender_info_hover on
the sender name (which causes it not
to launch the user menu)
This fixes some annoying copy-paste issues we've seen with users
accidentally getting a weird invisible unicode character in their URL
format string when trying to copy-paste an existing linkifier to
use for a new linkifier.
Fixes#10828.
We now use 10px to the left of major elements in
left sidebar.
And we then explicitly use 19px for the following:
icons in top left
indent for (more conversations)
stream hashtag icons
stream lock icons
We also kill off 2px of gutter that was caused
by whitespace in the HTML (and was slightly messing
up alignment of names beneath "Private messages").
Finally, we make the topic indent a bit more explicit.
In this commit, I've added a feature to unstar all the starred
messages. This is useful, e.g., for folks who are using starred
messages to keep track of things they should come back when next at
their desktop.
The event flow is the standard one for a feature with a confirmation modal:
(1) User clicks on unstar all messages.
(2) We display a confirmation modal; if the user confirms, we send a
request to the backend to clear all starred messages.
(3) The events system sends that UI update back to us, removing the
stars from the UI.
Fixes#11401.
We no longer have an empty message_content div for
messages like this:
/me gets some coffee
This requires a minor change in how we compute the
position of the message for editing.
The previous commits made the "arrow" class no longer
necessary for these left sidebar elements.
The "arrow" class was always a bit dangerous, as bootstrap
has a class by the same name for a different concept.
We weren't really using consistent styling for "arrow"
across all our chevrons, so even without bootstrap in
play, it was just creating complexity.
Using a more specific class avoids confusion related
to the .arrow class, which is not only a popover concept,
but also a Zulip concept in the left sidebar.
The topic-sidebar-arrow chevron never shows
here--it was just cargo-culted code from
the topic lists.
It's also a landmine--we don't want to
accidentally build a topic-related sidebar
menu for PMs.
We could arguably just use zero-unreads everywhere,
but we definitely don't want zero-topic-unreads
inside our PM list.
I prefer to just have these two concepts:
zero-pm-unreads
zero-topic-unreads
And it's super easy to share CSS properties for both.
When the user logs in as an admin, and clicks on the 'edit user'
button under the url path #organization/user-list-admin, the modal
that was displayed didn't contain the user's email address under the
list of information. This commit adds the email input as a readonly
element, which at the very least provides helpful confirmation that
you have the right user.
Fixes part of #11453.
Add a background highlight to vote count button if currently
logged in user votes on that option.
Tweaked by tabbott to use better variable names and Rishi for better
styling.
This is the real guts of how we render messages.
It only excludes the border effects, which we
leave in single_message.handlebars.
This is a pure code move, and should remove a lot of nesting that
would otherwise clutter one's view.
The bool `include_sender` will always be `true`
for status messages. Here is the relevant
excerpt from MLV:
message_container.status_message = // ...
message_container.include_sender = true;
We don't need the `include_sender` check in the template.
We could probably also fix the above code, but it's
semantically correct. I mostly care about simplifying
the template.
This is a pure code move. All three places where we use
this partial had the exact same markup, except one place
where I think `auto-select` was inadvertently left off.
This is a pretty coherent chunk of template code
related to these icons:
- edit pencil
- reactions
- chevron
- star
Moving it to a partial will simplify future diffs
where we re-work the message HTML.
This is a pure code move.
Some changes here:
* more whitespace
* avoid else, and just re-state the condition
* avoid long if blocks, just re-state the condition
* use standard `{{#if foo}}` construct
The refactoring of conditionals here will make more
sense in subsequent commits.
Fixing this involves fixing the backend to handle unchanged field
submissions of the Zoom credentials without trying to re-validate the
credentials (for performance) as well as to fetch the already-sent
secret.
Visually, #zoom_help_text acts like
.organization-settings-parent div:first-of-type when the Zoom option
is selected, but isn't treated as such.
No visual change with the #google_hangouts_domain change; just there to make
the code more readable/defensible.
Accomplished by adding a function to clear the status message with
an empty string. The html is then updated to reflect changes without a
refresh.
Currently, it's a small hassle to clear a status message. This option
makes things a bit easier.
Fixes#11630.
The is_editable field includes topic edits, so we need a separate
field for whether to display these icons which are all for content
editing.
Fixes#11666.
This commit achieves two things:
1. Changes the UI of the "Create stream" form to make the
textarea previously used to get the stream description
a simple input field of type text (to suggest a single
line description).
2. Adds an extra check on the frontend side to make sure that
when users create a new stream via. the "Create stream"
option in the settings panel, they can't enter any newline
characters (i.e. we disallow the enter key from being
registered when typing out the stream description).
We must also make sure that they cannot copy-and-paste over
descriptions containing newline characters.
resolves#11617
This is mostly adding markup, calling some convenient
functions in buddy_data.js, and adjusting CSS.
To make the circles update dynamically, I mostly
orchestrate this though activity.js for now. It's
possible we'll want to adjust that eventually to
happen through something like a `presence_events`
dispatcher, but that's essentially what
a good part of `activity.js` does now.
We now have a function get_user_circle_class
that returns one of these values:
"user_circle_green"
"user_circle_orange"
"user_circle_empty"
And we put that in the templates.
And then CSS renders the circle of the appropriate
color.
The unit tests now explicitly capture whether
we are rendering the correct kind of circle.
This fixes a longstanding UI issue when you have way too many recent
private message conversations, as you can now scroll down the list to
find what you're looking for.
Fixes#5384.
This removes the left border extending the stream label from the
recipient bar in from the drafts in drafts modal. Those borders are
important in the message feed for containing several messages, but
here we're only ever going to show individual drafts, and this change
avoids potential color clashes with the blue box surrounding the
recipient blocks.
Previously, this was only available in the Zulip development
environment.
Further work is needed on documenting this and how to use it for
managing work to follow up on.
This adds date dividers within a single message group when the only
reason we had previously been splitting apart two message groups is a
change of date. The overall effect is a cleaner message list user
experience.
The downside of this change would be that the recipient bars no longer
will always show a new date for date changes; to fix that, we rewrite
how the floating recipient bars both set the date field on the
floating recipient bar itself, as well as ensure that non-floating
recipient bars don't show duplicate dates.
In a future design update where we modify how message recipient bars
look, we may very well be able to simplify this logic by removing some
of the dynamic nature of the recipient bar calculations. But this is
a good implementation of what remains.
Tweaked significantly by tabbott from Steve Howell's original, both to
extract these changes from a larger PR as well as to modify the
first_visible_message logic to handle some tricky corner cases.
Fixes#10171.
The message_edit_history UI was incorrectly inheriting its content
div's structure from message_edit_content, i.e. the form for editing
message content, and not message_content, i.e. the class for rendering
the content of messages in the message feed (which we also use for
drafts).
Fix this by changing the inheritance, while also adding a (currently
unused) class for any future customizations.
Fixes: #5629.
This code will correctly add video call link to the message
textarea based on whether 'Add video call' was selected from
message composition form or message edit form.
The implementation was semi-rewritten by tabbott to remove an
unnecessary global variable, with fixes for the unit tests from
showell.
Fixes#11188.
This is primarily a feature for onboarding, where an organization
administrator might send a bunch of random test messages as part of
joining, but then want a pristine organization when their users later
join.
But it can theoretically be used for other use cases (e.g. for
moderation or removing threads that are problematic in some way).
Tweaked by tabbott to handle corner cases with
is_history_public_to_subscribers.
Fixes#10912.
This replaces the current usage of stream names with stream ids.
This commit also removes the `traditional` attribute from the invite
form as now we are sending stream_ids as an argument; this was the
only place in the codebase we used traditional=true, and it's great to
have it removed.
We now compute the class that drives the tiny
green/orange/empty dot in the user popover using
the same logic as the buddy list.
This was broken in the early implementation of
set/clear-away, but it was never released.
Fixes#11413
The only time we set the `home` flag to true
is when it's the last (and only) item in the
list, in which case we flip `hash` to false
at the end of `make_tab_data()`.
So the section of code where both `home` and
`flag` were true is dead code.
Also, we can use `else` instead of `unless`.
We had initially designed the poll widget like a blog
post with comments beneath it but it makes more sense
to think of it as just a simple poll with options.
When you hover over a user that has set a user
status, we now show something like "out to lunch."
You can test this in the console by doing:
user_status.server_update({status_text: 'out to lunch'})
And then hover over your name in the buddy list.
This adds a setting under "Notification" section of
"Organization settings" tab, which enables Organization administrator to
control whether the missed message emails include the message content or
not.
Fixes: #11123.
This commit takes away the ability for non-admin members to create
streams where only admins can post messages by hiding the option from
them.
Fixes#11290.
NOTE: If you revert this commit, you want to revert
the immediately prior commit as well. The history
is that Ishan made some improvements to the widget,
but there were some minor bugs. I decided not
to squash the commits together so that the git
history is clear who did what. (In particular, I
want questions about the JS code to come to me if
somebody does `git blame`.)
Anyway...
This is a fairly significant rewrite of the polling
widget, where I clean up the overall structure of
the code (including things from before the prior
fix) and try to polish the prior commit a bit as
well.
There are a few new features:
* We tell "other" users to wait for the poll
to start (if there's no question yet).
* We tip the author to say "/poll foo" (as
needed).
* We add edit controls for the question.
* We don't allow new choices until there's
a question.
This also fixes few unusual UI issues like an invitation got failed when
certain emails can't be invited then the error box is left with "warning"
even when next request got succeed and another case when invitation got
succeed after failing it's still reported with "alert-error" class alert
banner.
The legacy "Updated Successfully" message shown after saving changes,
is removed, and replaced with our standard "Saving" spinner and
animation.
Fixes: #11177.
This code will correctly render emoji to the message textarea based on
whether emoji was selected from message composition form or message
edit form.
Fixes part of #11188.
Add explanation in popover on disabled add-subscriptions input elements,
admin can't add subscribers to non subscribed private streams, only
subscribed users can.
Fixes#10593
This makes it possible it include our standard markdown formatting in
one's custom profile fields, allowing for links, emphasis, emoji, etc.
Fixes#10131.
While we're at it, we remove the JSON parsing that was part of the
user field code path, since this function isn't responsible for
rendering user fields.
We instead get the specific fields from message
that we use. This is particularly helpful
for subject -> topic migration; we no longer
have to account for "subject" fields in
client-side templates.
This adds a new realm_logo field, which is a horizontal-format logo to
be displayed in the top-left corner of the webapp, and any other
places where we might want a wide-format branding of the organization.
Tweaked significantly by tabbott to rebase, fix styling, etc.
Fixing the styling of this feature's loading indicator caused me to
notice the loading indicator for the realm_icon feature was also ugly,
so I fixed that too.
Fixes#7995.
Fix an issue that when a message is being edited, sometimes compose
options are hidden if there is no time limit. Also, move the options
further from the time limit to make them more noticeable.
Fix#11056.
Also, add a new notification sound, "ding". It comes from
https://freesound.org, where the original Zulip notification sound comes
from as well. In the future, new sounds can be added by adding audio
files to the `static/audio/notification_sounds` directory.
Tweaked significantly by tabbott:
* Avoided removing static/audio/zulip.ogg, because that file is
checked for by old versions of the desktop app.
* Added a views check for the sound being valid + tests.
* Added additional tests.
* Restructured the test_events test to be cleaner.
* Removed check_bool_or_string.
* Increased max length of notification_sound.
* Provide available_notification_sounds in events data set if global
notifications settings are requested.
Fixes#8051.
This ensures the "account settings" UI for managing a user's own email
address uses the delivery email, since that's what users care most about.
Eventually, we'll need to add support for at least viewing both email
addresses in "account settings", but this is the right long-term
behavior.
This new setting is still hidden in the UI when not in the development
environment, because the feature isn't ready for production, but
merging this will help simplify future work on the feature.
When the list of recipients of a group private message conversation is
truncated due to being long in the "Private messages" area, we didn't
provide easy access to the full list of people. Fix this by adding a
title attribute for the area.
Fixes#10978.
This correctly shows guest users that they cannot interact with
anything in the "Organization" tab, though we preserve the read-only
access to it so that they can (e.g.) browse the organization's custom
emoji.
Previously, because the parens were added via CSS, copy-pasting the
EDITED notices resulted in junk like this:
Iago 3:51 PMEDITED
edited message content
Now, you get:
Iago 3:51 PM (EDITED)
edited message content
Status messages were incorrectly not selectable, due to a bug in how
we setup the no-select hierarchy (for making copy-paste not have weird
whitespace issues).
Fixes#10456.
For message groups, I just changed the internal name
to "topic_links".
For uses of "subject_links" that are tied to how the
server names fields, I introduced these wrappers:
* util.set_topic_links(obj, topic_links)
* util.get_topic_links(obj)
These can be used for either messages or events.
Previously, messages were a string of disconnected regions. Modeling them as a list brings several benefits:
* Quickly jump to the message list by using a screen reader's list navigation hotkey.
* Quickly jump between messages by using a screen reader's list item navigation hotkey.
* Quickly jump to the beginning or end of message lists in screen readers that support it.
Change wording of public stream description to
"Any member of the organization" from "Anybody"
to indicate that guest users can't subscribe even
public stream of organization.
This moves the deactivate account which was previously placed under
"SETTINGS / YOUR ACCOUNT" -> "Deactivate account" to "SETTINGS / YOUR
ACCOUNT" -> "User settings" for making it more visible.
When a user clicks the compose `+` button, create a popover at the
bottom right of the screen including buttons for opening a new stream
message or a new private message.
The "notification settings" page previously advertised support for
mobile push notifications via checkboxes, even if the server hadn't
yet been registered for push notifications. This was a frequent
source of onboarding pain for new Zulip organizations.
We fix this by providing a clear warning and disabling the relevant
inputs on the settings pages.
Modified significantly by tabbott to correct some tricky logic errors
as well as some copy-paste bugs.
Fixes#10331.
This supports guest user in the user-info-form-modal as well as in the
role section of the admin-user-table.
With some fixes by Tim Abbott and Shubham Dhama.
This deduplicate code for the checkboxes which are dependent on other
parameters and it makes no sense changing them when that parameter is
false. For example, changing `message_content_in_email_notifications`
makes sense only when `enable_offline_email_notifications` is true.
This module makes it really easy to create are-you-sure
dialogs for dangerous operations.
Basically it's one function with five parameters. You
give three chunks of HTML, a callback function, and
a parent container.
The first use of this will be in settings_user_groups,
coming up in a couple commits.
Since now we have email notifications for streams messages too, so
there is no direct dependency of
`message_content_in_email_notifications`checkbox on
`enable_offline_email_notifications` setting and neither we can say it's
dependent on `enable_stream_email_notifications` as well because we may
have email notifications set for individual streams. So removing this
checkbox dependency is the best solution here.
This is largely inspired by requests from people not liking the
Google's new emojiset. A lot of people were requesting to revert
back to old blobs emojiset so we are re-enabling this feature
after making relevant infrastructure changes for supporting google's
old blob emojiset and re-adding support for twitter emojiset.
Fixes: #10158.
This adds a feature in the "Notification" section of "Settings" tab,
which lets user enable or disable login emails notification.
Tweaked by tabbott to simplify the test.
Fixes: #5795, progress towards #5854.
Empty "person picker" fields appear with a much smaller width than all
other custom fields. Increase the `min-width` of the field that it
matches the widths of other text boxes.
Fix#10414.
Modify structure of template data used to render
`user_profile_modal.handlebars`.
This is preparatory commit to display user pills in user profile
popover instead of user names in user type custom fields.
This commit add FIELD_TYPE_CHOICES_DICT to page_params and replace
FIELD_TYPE_CHOICES.
FIELD_TYPE_CHOICES_DICT includes all field types with keyword, id
and display name. Using this field-type-dict, we can access field
type information by it's keyword, and remove all static use of
field-type'a name or id in frontend.
This commit also modifies functions in js where this page_params
field-types is used.
This line full of non-breaking spaces dates back to before Zulip being
open sourced (ca4e6a0ff), so we can assume it was a fix that we don't
need anymore.

Users in the waiting period category cannot subscribe other users to
a stream. When a user tries to mention another unsubscribed user, a
warning message appears with a subscribe button on it to subscribe
the other user.
This commit removes the subscribe button and changes the warning text
for users in the waiting period category.
Instead of displaying a fixed error message inside the yellow bar itself,
now the yellow bar disappears on error and a red compose_error is shown.
The error message is the one returned from the server.
Due to copyright issues with potentially displaying Apple emojisets on
non-apple devices, as well as iamcal dropping support for the emojione
emojiset (see https://github.com/iamcal/emoji-data/pull/142), we are
dropping (perhaps temporarily) support for allowing users to switch
emojisets in Zulip.
This commit just hides the feature from the user but leaves most of
the infrastructure in place so that in the future if we decide to
re-enable the support we will not need to redo the infrastructure work
(some JS-side code is deleted, mostly because we'll want to re-add the
feature using the do_settings_change infrastructure anyway).
The most likely emoji set to add is the legacy "blobs" Google emoji
set, since it seems popular with some users.
Tweaked by tabbott to remove some additional JS code and update the
changelog.
