Include dependecies to get the app started.

I was unable to boot the rails app without including 2 gems that Less
requires (see: https://github.com/seyhunak/twitter-bootstrap-rails).

Once those gems were bundled, then I needed to re-run the generator for
less as well:
  rails g bootstrap:install -f
...which resolved an error that the app was throwning
(http://stackoverflow.com/questions/13708303/variable-fontawesomeeotpath-iefix-is-undefined).
Update Rails.

This resolves a major security vulnerability, and will ensure future
users of the app bundle with the latest version of the 3.2 branch.
