* Update interim-bootstrap to use the partials from bootstrap-sass,
since some of the names have been changed (and we're using the
Bootstrap 2 javascript now). This should make it easy to keep the
file up to date with the version of Bootstrap we're using.
* Use interim-bootstrap instead of bootstrap-complete in default.css to
avoid the little problem I ran into with Bootstrap + Blueprint grids
not getting along. :)
* Revert the CSS class change (from .span-24.last to .row) in
layouts/application since interim-bootstrap works around that problem.
* Get rid of .icon-black since it's not needed.
* Remove the 60px padding on the page body since it isn't needed and
causes problems with the single post view.

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. :)
