This new setting controls whether or not users are allowed to see the
edit history in a Zulip organization. It controls access through 2
key mechanisms:
* For long-ago edited messages, get_messages removes the edit history
content from messages it sends to clients.
* For newly edited messages, clients are responsible for checking the
setting and not saving the edit history data. Since the webapp was
the only client displaying it before this change, this just required
some changes in message_events.js.
Significantly modified by tabbott to fix some logic bugs and add a
test.
`add_emoji_by_admins_only` backend setting is represented by page_param's
`realm_add_emoji_by_admins_only` attribute. When this setting was changed
we were wrongly updating the `add_emoji_by_admins_only` attribute which
doesn't exist.
This system hasn't been in active use for several years, and had some
problems with it's design. So it makes sense to just remove it to declutter
the codebase.
Fixes#5655.
Added a dropdown in the organization settings page with a search-box and
required styles. Also added an element to disable it. Added a method to
populate the dropdown using list_rendering.js. Also altered response to
the event of deletion of the notifications stream on the frontend. On
selection of a new stream or on clicking 'Disable', a patch request is
made with stream-id to /json/realm.
Fixes: #3708.
