Introduce the Builbot Tool.

This plugin will submit a patch to a buildmaster using the buildbot
try command.

At the moment, PB authentication is the only working authentication
method. SSH functionality is there, but buildbot itself is broken.
Updated Buildbot plugin.

I updated the BuildBot plugin for reviewbot so that it works with the
new api.
WIP: Adding UI for manual trigger of Review Bot.

Hook the Review Bot extension into the Review Board UI and added a
lightbox for manual trigger of Review Bot tools. Also includes new API
resource for pulling down installed tools.
Update setup.py files.

Change some of the arguments to setup in preperation for a 1.0 release
after the rework. These changes should make the extension a new
extension in the eyes of Review Board, instead of just an update. This
is probably beneficial since things will be restructured quite a bit.
Update the data model.

The Models for the extension have been changed to add support for the
upcoming features. These changes completely break the extension until
the supporting code is updated to use the new Models.
Remove the evolutions and update templates dir.
Dump WIP model modifications.

Some of this stuff has been sitting in my working directory for far too
long. Much of this is WIP, this totally breaks the tree, but it needs
to be out there to collaborate.
Drop more WIP changes.

This stuff is all over the place.
