Prior to this change, any stream message sent by internal_send_message
could only be in the realm of the sender.
This was a problem most notably for... the tutorial bot, with the
hilarious consequence that the tutorial worked fine in humbughq.com,
but failed to start anywhere else.

With this change,
pkill -SIGUSR1 -f runtornado
will dump the stack and SIGUSR2 will enable an interactive debugging
session.
This fixes#613 for Tornado which was the original motive for that
ticket; I'm not sure whether we want to do this for our Django
processes as well, but it would be easy to do so if we did.

Even though they look like images, they're not -- you need to

At Ksplice we used /usr/bin/python because we shipped dependencies as Debian /
Red Hat packages, which would be installed against the system Python. We were
also very careful to use only Python 2.3 features so that even old system
Python would still work.
None of that is true at Humbug. We expect users to install dependencies
themselves, so it's more likely that the Python in $PATH is correct. On OS X
in particular, it's common to have five broken Python installs and there's no
expectation that /usr/bin/python is the right one.
The files which aren't marked executable are not interesting to run as scripts,
so we just remove the line there. (In general it's common to have libraries
that can also be executed, to run test cases or whatever, but that's not the
case here.)

Previously we were doing 100 queries for new messages being sent to
the main hacker school channels; they were faster than many similar
instances because they were all done within 1 transaction, but still,
send_message_backend would be spending up to 200ms (and 148 queries)
querying the database with the previous code on prod; this new version
should do a fixed number of database queries per message.

To work around the issue we're having with queue draining between
parallel blocking connections, use the same rabbitmq queue for both
activity and presence events, keyed on a 'type' flag in the message
itself.

This cuts the MIT Zephyr home page load time and also #subscriptions
database-sourced load time for me from about a second to about 50ms on
my laptop. The home page still takes about 600ms to load due to
templating.

SimpleQueueClient was not thread-safe as the pika method
calls that we are using might disconnect and end up in a bad
state if two threads enqueue messages at the same time.
In order to avoid this, each user of the rabbitmq queue
gets its own instance of a SimpleQueueClient.

Code like this is dangerous:
class SimpleQueue(object):
queues = set()
because all instances will share the same 'queues' set object.
We don't really need multiple instances, but neither is there a reason to break
them. So do the normal Python thing instead.

This will give us flexibility in the future to add new properties to the
list.
In order to support that, we now do a list comprehension rather than just
returning the gather_subscriptions list in get_stream_colors.

Supporting ``` as a code fence marker complicates the auto-fence
closing, and as per a discussion with Keegan on code-review@, it
is not worth the extra complexity.

We need this so that we can safely expunge old events without interfering with
the running server. See #414.

Before this is deployed, we need to install rabbitmq and pika on the
target server (see the puppet part of this commit for how).
When this is deployed, we need to start the new user activity bot:
./manage.py process_user_activity
in the screen session on the relevant server, or user_activity logs
won't be processed (which will eventually result in all users getting
notifications about how their mirrors are out of date).

This is syntax like

This is not very useful for short chat-style messages. It will confuse users,
especially because we don't document it. And disabling it saves the effort of
applying the same link fixups as elsewhere.

These get automatically re-numbered, which will do the wrong thing when people
split their lists across multiple messages.
