Upgrade our current Bootstrap 1 and 2 dependencies to use Bootstrap 2.0.2
from the bootstrap-sass gem.

I had to modify layouts/application to get the stream page to render properly,
looks like a slight conflict between Bootstrap and Blueprint grid systems, with
.span-24 instead of .row I was seeing the whole right bar dropped to the bottom
of the page below the left bar.

I also modified two other templates since Bootstrap 2.0.2 includes a "badge"
class that was making our navbar badges look funny. :)
