This saves something like 15ms on our 1000 message get_old_messages
queries, and will save even more when we start sending JSON dumps into
our memcached system.
We need to install python-ujson on servers and dev instances before
pushing this to prod.

I've tried to do this in a way that's scalable and easily configured,
so that we can add new such filters for customers on-demand without
needing to add anything other than a bit of configuration.
Once we're confident in the arguments to this system, I think we'll
want to move the regular expression lists into the database so that we
don't need to do a prod push to modify the regular expression lists.
The initial set of regular expressions are:
(1) Linkifying e.g. "trac #224" in the Humbug realm, so we're exercising this code.
(2) The various ticket number things CUSTOMER7 uses for the CUSTOMER7 realm.

We get too many error reports from it, which is bad for us actually
fixing the other errors that we do have.

There was no benefit to our various link processors all doing
independent scans through the list of messages, and this makes it much
easier to understand the logic of how each link will be handled, and
also makes policies like "don't process links if there are more than 5
of then" easier to implement coherently.

Since we log to statsd our cache time lookups by cache key, using a unique
tweet id for each lookup was just filling up our cache without being useful.
Also, log database cache lookups in a further namespace to distinguish between
memcached caches

For sites that are supported, we now grab thumbnails for images + video
embed code for videos and use them in lieu of our existing embed code.
We also embed rich non-script content.
Special casing is done so that we don't embed images twice.
Some testcases were modified to avoid triggering Embed.ly
The manual step is to install python-embedly.

Timing out within the Twitter portion of the render causes the message
to still go through (without a preview). If we don't timeout here, it
causes the entire Markdown render to timeout, which rejects the
message in its entirety -- a far worse outcome.

This will automatically fix bugs such as one in which
internal_send_message didn't properly strip() the subject argument
before sending a message.
We change the recipient_type argument to internal_send_message to take
the recipient type name (e.g. 'stream') both to better fit the API and
also because the previous code incorrectly handled huddles.

Sometimes Dropbox shares with /s/ and sometimes with /sh/,
and I'm not sure which controls it, but we should deal with both.

This avoids our repeatedly retrying to fetch a tweet that doesn't
exist from the Twitter API.

This should substantially improve the repeat-rendering time for pages
with large numbers of tweets since we don't need to go all the way to
twitter.com, which can take like a second, to render tweets properly.
To deploy this commit properly, one needs to run
./manage.py createcachetable third_party_api_results

This commit adds a dependency on python-twitter,
whose upstream is at https://github.com/bear/python-twitter,
and which for now needs to manually be installed on our
servers from the Debian package in sid.

This uses the unauthed v1 of the Twitter API, which is going to go
away soon, but it's fine as an interim measure.
