The key property is that we never reveal the non-public directory name
4nrjx8cwce2bka8r to a not-logged-in user. This makes it less likely that
random people from the Internet will download all our client code while we're
still in private beta.

Previously if you tried to send to "a b", we actually ended up trying
to send to "a%20b", since we were url-encoding the stream name and
then not properly decoding it.

PgUp, PgDn will already call the scroll handler, which will
of its own accord call keep_pointer_in_view.

We'll use this internally for the commit bot. We might eventually disable it
for external users.

That andSelf is only necessary if a .recipient_row were immediately
followed by a .bookend_tr, which, I don't know, after a redesign could
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:

There was this very cute problem where if you were narrowed and
scrolled to the top of the page, you couldn't seem to click on the
stream or subject name.
The issue was: the floating_recipient_row div was visibility: hidden,
which means that it made top_statusbar big enough to cover up that top
part, capturing the clicks.
So instead we make top_statusbar also visibility: hidden so that
the clicks get through.

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.

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.
