Kuva needs to be loaded into the layout of the main Rails application, so let's remove the unused application template and let the Kuva::ApplicationController inherit from the ApplicationController of the main Rails application.
There are no images in the Kuva engine, so let's remove this.
Moved the external assets into a separate directory called /ext.
Instead of an application.js file we're now using the base.js.coffee file which requires everything.
Split up the styles into separate Sass partials and renamed the application.css file to base.css.sass which requires everything.
Instead of including the actual jquery file, we're now using the jquery-rails gem.
Added the AssetsGenerator which copies the base CoffeeScript and Sass files to the Rails application.
