ReviewBoard Performance Enhancement

[Stephen Gallagher]

I have built a new version of ReviewBoard which will hopefully solve the 
performance issues we were seeing on Hosted.

On PT9, the upstream patch I pulled into this release reduced my login 
time from 10-12s (as measured by yslow) to 2-4 seconds. I'm hoping it 
will have roughly the same effect on hosted.

Basically, the upstream patch fixed a long-standing issue where 
ReviewBoard was making a separate DB call for every resource that the 
dashboard (the UI) uses. This patch reduces the number of calls 
significantly, instead opting for grabbing a wider selection of the data 
all at once.
