Because we're storing 25,000+ message content objects in memcached on
server restart, we were sometimes exceeding the 64MB cap even during
the restart process. 256MB should be safely large enough to not have
the issue but not so large as to seriously consume resources on our
app frontends (which currently have 7GB of RAM).

Also improve display of times passed -- we now use display short times
in milliseconds for easier reading.

Previous we had around 4 copies of the logic for deciding whether we
should publish data via a SimpleQueueClient queue, a
TornadoQueueClient queue, or to directly handle the operation, which
resulted in their getting out of sync and buggy (see e.g. the previous
commit).
We need to add a lock around adding things to the queue to work around
a bug with pika's BlockingConnection.
I should note that the previous logic in some places had a bunch of
tests of the form "elif settings.TEST_SUITE" for doing the work that
would have been done by the queue processor directly; these should
have just been "else" clauses -- since we generally want that code to
run on development environments whether or not the test suite is
currently running.

Previously we had several files which initialized SimpleQueueClient()
for sending items to the UserActivity queue, even though those code
paths aren't used outside Tornado. This resulted in slower Tornado
startup times.

The actual database query that we use to fill the UserMessage cache
only takes a few hundred milliseconds to run; however the process of
iterating through the results would take 3-5 seconds because the
Django ORM is not very efficient for small tables where we're only
interested in the integer values in a couple columns.
So we can save most of that Tornado startup time by just doing this
one query manually; I left the original query next to it in a comment
so it is easy to keep it all up to date as we change our product.

This only does something if DEBUG=False, but it's now required that
you set this on Django 1.5 or the server will silently serve up 500s
for every request (not the best failure mode).

See http://bugs.python.org/issue5876 for an explanation for why this
is needed -- basically __repr__() needs to return a string, not a
unicode object in Python 2.
This causes problems on Django 1.5 because the more expressive
exception code in model.objects.get() will crash with a __repr__()
containing non-ascii unicode characters.

Checked using the following (relevant for rebasing):
git grep url templates/ | grep -v "'django" | grep -v "'zephyr"
This appears to not have a good backwards-compatability story (well,
there is one involving a %load from the future, but it seems to not
work).

We made this change for performance reasons that don't exist now that
we only render a small portion of your messages, and it causes a
distracting flicker when you scroll through messages slowly.

Those examples make the tutorial feel much longer, and they aren't
relevant to people who aren't using Humbug to talk about code.

It's not so black and white in a world where we auto-scroll at the
bottom, and we've observed that people trying Humbug over-focus on it.

This is a lot cleaner, and also cuts about 50-70 ms off of page load time in
local testing (with lots of users), presumably because there's less work to be
done by the slow Django template engine.

This fixes tests that have been failing for me for, well, months, that
I've been ignoring:
======================================================================
FAIL: test_successful_subscriptions_list (zephyr.tests.SubscriptionAPITest)
----------------------------------------------------------------------
Traceback (most recent call last):
File "/Users/jesstess/dev/humbug/zephyr/tests.py", line 631, in test_successful_subscriptions_list
self.assertIsInstance(stream['name'], str)
AssertionError: u'Denmark' is not an instance of <type 'str'>
======================================================================
FAIL: test_get_stream_colors (zephyr.tests.SubscriptionPropertiesTest)
----------------------------------------------------------------------
Traceback (most recent call last):

----------------------------------------------------------------------
The more comprehensive fix to this is going through both our API and
JSON calls and ensuring that we always return unicode objects,
documenting that, and then testing that more specifically. For now, at
least have passing tests.

This fixes an experienced bug where you couldn't subscribe to a stream
with non-ASCII characters (failing with a UnicodeEncodeError), as well
as many other potential bugs.
