Previously we were generating API keys deterministically using a hash
of the user's email address; this is clearly not a good long-term
approach.

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

Messages that get sent out when someone subscribes many people to a new stream each
cause individual database queries (and their associated transactions). With the patched
bulk_create (which sets the .id on created objects), we can reduce this query down to a constant
number of queries on the Message and UserMessage tables.
Note for deployment (local dev, staging and prod):
you must be running a patched django, found here: https://github.com/acrefoot/django/branches
use this branch: acrefoot-bulk_create_with_id-1.5.1
on acrefoot-bulk_create_with_id-1.5.1

We also record the historical edits to the message in this JSON format:
[{"prev_content": "new test message 14", "timestamp": 1369157249},
{"prev_content": "new test message 13", "timestamp": 1369157118}]
but we don't actually do anything with the information as of yet.

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.

Currently the interface for editing messages is limited to a
command-line API tool; it's great for testing with e.g.:
./api/examples/edit-message --message=348135 --content="test $(date +%s)" --site=http://localhost:9991 --subject="test"
The next commit will add a user interface for actually doing the editing.

This, combined with acrefoot's work on sending the notifications in
bulk, resolves trac #1142 -- we do only 10 database queries and the
whole operation completes in about 300ms on my laptop.

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

Users can send to any stream except invite-only streams that they
aren't subscribed to. Bots can send to any stream except invite-only
streams that neither they nor their owner is subscribed to.

After this change, the memcached time consumed by doing
get_old_messages for 200 and 1000 messages respectively now look like
this:
200 63ms (mem: 6ms/3) (db: 4ms/2q) /json/get_old_messages
200 178ms (mem: 67ms/2) (db: 6ms/1q) /json/get_old_messages
which might help explain where the time is going on prod for some of
our slower queries.

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.
