That andSelf is only necessary if a .recipient_row were immediately

very well be the case, so let's guard against it now, especially since
our performance on scroll is currently pretty good.

In my limited trial, this sped the call up, on average, from
0.507ms to 0.473 ms... so, admittedly, not a lot.
I think this is a little conceptually cleaner, though, and it handles
the common path with the least work, which I like.

nextAll/prevAll walks the entire DOM, basically.
This code only walks the DOM until we find a new .message_row.
This speeds up the average time of a call to this function from about
6.38ms to 0.678ms, in my benchmarking.
Admittedly, the whole outer loop here could still use some
optimization, if we want to; do we really need to call this 1000
times?

http://api.jquery.com/first-selector/ mentions that using ":first" in
query selectors can be a little slow since we can't use the browser's
native querySelectorForAll implementation.
In my tests, this cut the average time down from 6.70ms to 6.38ms.
So, not great, but this function is most frequently called
many times in a big while loop, so, better than nothing.

If the client is not composing a message, we can just force a page
reload. However, if he is composing a message, we must preserve that
message while still reloading as soon as possible.
We take the following approach: if the client has not completed the
composition after 5 minutes, do a compose-preserving reload
(described below). If he sends the message before the timeout
expires, reload the page after a successful send. If the send fails
(not due to server timeout), however, we do a compose-perserving
reload in case the error was due to the data format changing. If the
send failed due to server timeout, we don't reload because the reload
will probably also fail.
In a compose-preserving reload, we redirect to an URI that has a
fragment indicating we are doing a reload and containing all the
necessary information for restoring the compose window to its
previous state. On page load, we check the fragment to see if we
just did a compose-preserving reload, and, if we did, we restore the
compose window (or just try the send again in the case of send
failure). The URI fragment looks like:
(imported from commit af4eeb3930c24118e088057d4da456748fbd2229)
Given that we now look at the top of the pointer rather than the
bottom for this check, our previous 4/5 number was far too permissive
(and led to your selected message often getting covered up by the
compose window).
Anecdotally, this feels a bit better to me.
(imported from commit 39ca7924db56272f7e623708ce0125b2a7012656)
In particular, we had this issue on huge messages. Suppose you had a
huge message and were scrolling up from the bottom. Initially it would
get selected as the message underneath it was below the
threshold. Then, when you scrolled again we said "oh, well, the top is
too tall, it's also *above* the threshold" and moved the pointer back
down. So it glitched back and forth.
Now we consider you above the view threshold by looking at your
bottom, and below the view threshold by looking at your top, which
seems to resolve this issue.

When Bootstrap shrinks the divs down into 'tablet' mode, our selected
message might end up being even lower in the screen than it was before
(because more text wraps). But our scrollbar does not automatically
advance to keep it in view -- so we do it manually.
This implementation is a little hackish in that it does some
unnecessary recenter_view-ing in big views (which can be a touch
disorienting) to optimize recentering on resizing for small views.
If that behavior is annoying, we can deal with it by being
smarter about when we trigger the recenter code.

We had this fascinating behavior where pressing a down arrow near the
end of the page would advance the pointer, call recenter_view, which
would trigger a scroll event, which would call keep_pointer_in_view,
which would notice that we were at the end of the page and advance the
pointer again!
I split out that last part into its own function which is only called
on mousewheel events.

This also helps us manage checking, case-insensitive, for
subscriptions while preserving the casing used by the class creator
for display.
It also fixes a bug where the class_list would become out of sync with
your true subscriptions, allowing you to appear to send messages to
classes to which you had unsubscribed.

So what's now happening here is that the outer div (which we were
previously animating) doesn't get animated at all; instead it is
simply made visible or hidden.
I *believe* this means that it always continues to take the same
amount of space in the DOM; its being added and removed seemed to
cause a slight height-of-page change which caused the scrollHandler to
fire, causing the selected message indicator to move down the page.
So now that this height is fixed, we achieve the animation instead by
animating the inner div -- the one that actually contains the
composebox elements.
(imported from commit 95b2f95d52254e3792633460f42efaac27559efe)
The issue with the animation is that it removes the composebox div
when it's done -- or more relevantly, it "adds" it when the composebox
appears, which causes some DOM elements to get reshuffled slightly
which causes some jitter.
(Similar to what was happening with the email addresses earlier.)
So instead of using display:none, we play with visibility:hidden,
which causes the thing not to show up, but doesn't cause it to
lose its place in the DOM.

The new version is now the only codepath that we use in order to start
a reply to a message.
(imported from commit dd28316d2640fd5fd712f326690d480b7db59c4c)
Just for the record, here's what happened:
If you click on a class message to start a reply, then click outside
to unfocus, then click on a huddle message to reply to that instead,
the system would end up calling the focus handler twice and _then_ the
unfocus handler once (why are we unfocusing something? Because we
have two compose windows -- new_zephyr and new_personal_zephyr, and
we're switching between them). the end result is that we'd re-enable
hotkeys with that unfocus handler.
Fix this by being sure to explicitly disable hotkeys after we setup a
reply to a message.

This is somewhat experimental and we may need to work on the condition
when it shows up (or move it elsewhere).
Also, maybe it should say "Today/Yesterday" for times super close to
now -- the main issue with doing this is whether it needs to update

This actually is a bit cleaner than our last approach,

When you're at the top of the page, you don't get scroll events
anymore if you're scrolling with a mousewheel. So we need
to listen to mousewheel as well as scroll.

PageUp and PageDown no longer causes the pointer to refocus,
because those trigger scroll events.)

It turns out it's marginally easier for us to completely handle Home
and End ourselves rather than let the browser do it, because home
scrolls to the top of the page, but it does not select the topmost
message.
With PgUp and PgDn, the default browser behavior is fine,
but it seems like PgUp on a screen where you're already
"scrolled to the top" should not be a no-op.

.display_recipient or .sender you would have to check them against
eachother.
We also introduce a new narrow_classish command, which is triggered on
