Correctly enable the asset pipeline

* Add the Rails 3.1+ Bundler.require statement to config/application.rb
  (properly enabling the :assets group)
* Move handlebars_assets gem into the :assets group where it belongs. :)
* Downgrade sass-rails to 3.1.4 since enabling the :assets group exposed
  a known bug in sass-rails ~> 3.1.5 [rails/sass-rails#78].
