In the first cut at topic zoom, I was re-rendering the
streams list, but this created glitches with orphaned
list items. The reproducible bug was that unread counts
on unshown streams weren't updating.
In the new approach, I keep the elements more permanent, and
I just hide and show them as needed, either through jQuery
show/hide or permanent CSS selectors.
I got rid of toggle_zoom(), so that we just explicitly zoom
in and zoom out in all situations. In particular, when we
narrow, it's more clear now that only stay zoomed in when
we're narrowing to the same stream as before (including topic
narrows within that stream).
When you zoom in, the number of topics is no longer limited
to 30, since that was kind of arbitrary anyway. (In practice,
the number of topics is usually well under 30, anyway, due to
the way we track them on the client.)

When your left sidebar is zoomed to show just one stream,
there is a link to to show all streams again.

This commit doesn't actually add the final UI to zoom/unzoom
topics, because I want to keep those in separate commits, in
case we change how to enable the feature. But this commit
adds a toggle_zoom() function that zooms/unzooms topics.
Zooming is minimally invasive, because we don't really introduce
many extra elements to the UI; instead, we just make the list of
streams be a list of length one (i.e. the active stream). This
gives us a lot of stuff for free, basically, like unread counts, etc.

Nobody uses it, and it causes confusion. (How is it different from 'Home'?)
For now, leave in the ability to get to the narrow, although we may
ultimately want to do away with it as well.

* We now clear the validation errors when the input box is de-focused
* We make the left sidebar height accommodate the validation error messages

This needs to be deployed to both staging and prod at the same
off-peak time (and the schema migration run).
At the time it is deployed, we need to make a few changes directly in
the database:
(1) UPDATE django_content_type set app_label='zerver' where app_label='zephyr';
(2) UPDATE south_migrationhistory set app_name='zerver' where app_name='zephyr';
