Front end stuff added. All front-end dependences are managed through bower now (via the [bower-rails gem](https://github.com/42dev/bower-rails). The rails-jquery gem was removed for an updated version through bower. All these files are checked in so you guys don't need to install node and bower unless you want to add more yourself.

Basic three.js example is also added.
