We also record the historical edits to the message in this JSON format:
[{"prev_content": "new test message 14", "timestamp": 1369157249},
{"prev_content": "new test message 13", "timestamp": 1369157118}]
but we don't actually do anything with the information as of yet.

Most of the model logic pertaining to unread counts had been in
zephyr.js, along with a couple global variables. Now the code
is encapsulated in unread.js. It was a pretty straightforward
extraction with some minor method name changes. Also, a small
bit of the logic had also been in stream_list.js.

Currently the interface for editing messages is limited to a
command-line API tool; it's great for testing with e.g.:
./api/examples/edit-message --message=348135 --content="test $(date +%s)" --site=http://localhost:9991 --subject="test"
The next commit will add a user interface for actually doing the editing.

This fixes a pretty subtle bug where the window-focus handler
wasn't updating the unread counts in the title, but it was
hard to notice, because as soon as you moved the mouse, the
problem fixed itself.
Apart from fixing the bug, this patch eliminates the expensive
mouseover handler, which is a big win.
The fix to the window-focus involved some unrelated cleanup. I
decoupled update_title_count() from received_messages(), as the
former method will probably live somewhere else soon.
Also, in order to get window-focus to update the title count,
I went pretty deep in the stack and added a call to
update_title_count() inside of update_unread_counts(). This
fixes window-focus as well as restoring that behavior to
code paths that were calling received_messages().
You'll see that call to update_title_count() is now adjacent
to the call to update_dom_with_unread_counts(), which is
fairly sensible, but then are calls to similar methods like
notifications.received_messages() that happen higher up in
the call chain, which seems kind of inconsistent to me. I
also don't like the fact that you have to go through a
mostly model-based function to get to view-based stuff, so
there are some refactorings coming.

The problem is that if you load a browser window in a stream narrow,
add_message_metadata will be called for the messages in the narrowed
view before it is called for the messages going into the main view
(thus inserting them into all_msg_list), resulting in duplicate
copies of messages.
This would be mostly OK except that we call
process_message_for_recent_subjects inside add_message_metadata, and
that function assumes it is only called once on each message
(otherwise it'll double-count the message).

Created a function message_viewport_info() to return more accurate
effective viewport info and called it from process_visible_unread_messages().
Also killed off a tiny bit of dead code in process_visible_unread_messages().

This refactoring basically splits off two functions from update_unread_counts(),
which then becomes a simple three-liner.
The function get_unread_counts() is extracted, and it's purely functional
computation. It paves the way for a more pull-based approach to getting "unread"
counts, where other parts of the program can just call it to get values as
needed without worrying about side effects. It is staying in zephyr.js for
now.
The other function is stream_list.update_dom_with_unread_counts(), which
has a new home in stream_list.js. It handles all the DOM manipulation
aspect of unread counts in the left pane, mostly by delegating to smaller
functions within stream_list. Some of those smaller functions can now
be turned into private methods FWIW, but I'm not sure it's worth the
trouble.

This is a prefactoring to eventually eliminate the home_unread_messages
global variable. More commits to follow.
In order to set up process_loaded_for_unread() not to modify
global variable to get its job done, we want to pull it out of
add_messages(), so that add_messages() doesn't have to pass back
state to the 9 different places in the codebase where it's called.
There are only 2 places where process_loaded_for_unread() get
called after this commit.
In order to facilitate pulling up process_loaded_for_unread(), I
made it so that the contract for add_messages() was to accept
already-hydrated messages. This way I could hydrate the messages
before calling process_loaded_for_unread() without have to
worry about double-caching them in add_messages. This will
slightly improve performance, but it was mostly done for code
clarity.

This was a workaround for a number of other bugs we had, but at this
point just serves to make debugging more difficult.

Previously we never sent desktop notifications when the browser was
focused, even if the message appeared offscreen. After this commit
there are only a few cases when PM or other notifiable message doesn't
trigger a desktop notification:
(1) You sent it yourself
(2) It was onscreen when it arrived while your Humbug window had focus

The .height() and .width() functions are actually pretty expensive for
the number of times we call them. The viewport height and width
don't change often, though, so we can just cache them and recalculate
them on window resize.

The .height() and .width() functions are actually pretty expensive
for the number of times we call them. The callers of within_viewport
already know the offset and height of the row, so we just pass them
in so the values don't have to be recalculated.

We previously kept the lists in the DOM for all streams and updated
them all when new messages arrived. This was very expensive for
large numbers of streams, so we now just build the subject lists on
demand.

We memoize add_message_metadata by checking if the message is already
in the all_msg_list. Therefore, we need to add messages to that
message list before we add it to the narrowed_msg_list.

We were previously doing this on every message. Because
update_recent_subjects is linear in the number of streams in the
sidebar, this became very slow when we enabled the streams sidebar
for the MIT realm.

This fixes a bug where if you were narrowed to a search and received
a new message that belonged in that search, the message would appear
to have an empty subject and content.

In the case where we're getting old messages for a narrowed view, the
anchor message id might not actually be in the result set so there's
no reason to fetch an extra message.

Previously, our check for whether we needed to call load_old_messages
a second time on page load to get up to the present caused us to
basically always do such a call.
