basically this tries to turn scroll-the-world into not-scroll-the-world
This is not very good--maybe Allen has a better idea. The best solution would be to
turn off scroll-the-world. Look for it after the tables->divs change happens.

Previously, we would slowly accumulate duplicate copies of events that
happened while the user was in the tutorial at a rate of 1 copy per 5
seconds.

We now use window.innerWidth to check for CUSTOMER7's skinny
mode, which empirically seems to be more consistent with
CSS's max-width @media settings.
I tested under FF, Safari, and Chrome.

It's possible for a message to be considered "long" at one point,
and then if you narrow to it later, it should be considered "short",
because either the screen's wider or taller. This commit makes
sure that we remove the "condensed" flag from short messages,
and it also fixes the "More..." click handler's assumption that
could-be-condensed will always be true for condensed messages.

Cache the height of messages to speed up ui.condense_and_collapse()
to make narrows work more quickly. The height of the message
determines whether it is auto-condensed or not. We clear specific
cache entries when messages get edited, and we reset the entire
cache when the window width changes.

Trying to condense messages when they are not yet visible just
leads to wasted effort and wrong results.
This commit makes it so that current_msg_list always points to a
visible list, so the code related to message rendering knows when
to call ui.condense_and_collapse(). For activating narrows, we
now let rendering handle the condense/collapse case.
The home view situation is a little trickier, because we render
new messages in the home view even when we're inside inside of a narrow,
presumably to make it fast to switch into the home view. When
we actually go back to the home view, we need to sweep for messages
that might need to be condensed, since they have been originally
rendered while the home view was not visible.

Before this change, you could open the Administration page
for a 2nd time, and there would be two copies of each stream.
The simple fix is to remove any existing rows before populating
the table.

This is the "Tried to call a Dict method with an undefined key" error
because it tried to look up stream information for `undefined`.

There are now 2 cases for narrowing:
1. We narrowed, but only backwards in time (ie no unread were
read). In this case, try to go back to exactly where we were before
narrowing. This behavior is unchanged.
2. We read some unread messages in a narrow. Instead of going back to
where we were before the narrow, go to our first unread message (or
the bottom of the feed, if there are no unread messages). This is new.
This means that after catching up through the sidebar, on returning
home you'll be at the bottom of your feed.
Searching for the first unread message in a message list with 40,000
messages only takes 17ms according to:
function timeit() {
var t0 = new Date().getTime();
_.find(current_msg_list.all(), unread.message_unread);
var t1 = new Date().getTime();
console.log('Find first unread: ' + (t1 - t0) + ' ms');
}

This changes the algorithm slightly for the 2-block case, because
I simplified the logic to just divvy up the space naively based
on the relative size of the blocks.
(imported from commit 9498edd916f65e07fb64d138276691d0d5cc0e55)
This is a functional change. Before this change, the stream
list and user list were allowed to take equal space in the left
sidebar; now, we take the size of each list in deciding which
proportion each block gets.

I don't think share-the-love is turned on for CUSTOMER7 in the
first place, but even if it is, we should hide it when they go
into narrow mode, to make room for streams and users.

Calling $('#foo') is expensive, so if you need it twice, you
should store it in a variable. I did this for stream_filters
and user_presences, and added the expectOne() call for them as
well.

I'd also like to add a database table to actually store the values
that we get out of this and our send message requests for future
inspection, but for now, grepping logs+statsd is good enough.

I renamed ui.process_condensing() to ui.condense_and_collapse(),
and, more importantly, it now takes a list of elements, not a single
element, which allows us to do some computations outside the loop.
(imported from commit d5984088030c2a0d4ec8b258c7fcec3e84caf2b1)
This sets us up for the next commit, where we will change
process_condensing to loop over several elements, and we will
not need to recompute height_cutoff every time.

Without an explicit close, we will continue to get messages on the old
connection, even once we replace the _sockjs property. This leads to
"impossible" situations, such as receiving ACKs after reconnecting.

Now that this is no longer a known problem with our product, we want
to hear about it when it happens.
I worry a bit that a 2s fuse may be too aggressive for the case of
customers in Europe, but it might be OK.
