On my dev machine this cuts /activity load time with lots of users by more than
2/3. I expect the gains will be even greater in production due to the greater
relative cost of database queries.

Note that the tsvector cache column should be fully populated before

This allows us to remove fetch_colors() entirely, and should speed up page

We also JSONEncoderForHTML instead of dumps so that the result is safe

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.

Previously we checked if property was false after doing .strip(). Since
you can't call string methods on a NoneType, we were 500ing.
The code now does a normal dictionary get via [] and catches the
KeyError.

Returning json_error inside an inner function call will result in the error

Previously we made calls to the JSON api, which means that the API key

Before, it let you subscribe only yourself or one other person to
possibly many streams.
This is used by the subscriptions page to specify the subscribers when
you create a stream.

On my laptop, this cuts search time from several seconds down to
a few hundred milliseconds.
If we want even more speed, we could store the ts_vector as a column
on the message database. The Postgres documentation says this will
make "searches [...] faster, since it will not be necessary to redo
the to_tsvector calls to verify index matches." Going this route
requires creating a trigger to automatically insert the appropriate
column when new rows are inserted.
Note that the full text index must be fully created before this
commit is deployed. Full text search without an index is actually
significantly slower than using the LIKE operator.

This is for allowing us to do things more complex than returning a Q

Apparently short_name is not consistently the person's username
in our system -- for many MIT people, it's their full name.

As of this writing, short_name is the part before the @-sign,
and we already display the realm, so no need to display it
twice.

Eventually there should be a database table or something where we can

Right now we mitigate abuse by sending the principal user a Humbug

some sort of stream invitation system, instead.

Inspection of the postgres slow queries log showed that the "narrow to
personals with a particular user" database queries were taking a long
time to run (0.5s+). Further investigation determined that the OR
gate construction used here was causing the entire zephyr_message
table to be scanned; primarily I think because we were using the
implicit constraint that the logged in user had received messages.
This change makes that query explicit (improving performance), while
cleaning up the code to avoid an unnecessary query and read a little
more clearly.
After this change, the relevant database query takes 10s of milliseconds.

This essentially reverts d900957e468815bcb99de67d570dfd7ce4413220.
This code was consuming up to 50-100ms per client recipient of a
message, so for any messages that would go to 50+ browser windows /
mobile devices, it would take several seconds to run, during which
time Tornado would be completely blocked.
In the future, we can re-fix #174 using a cache of recently delivered
messages, so that this code block doesn't go to the database and thus
can run instantaneously.
