Angular Rails Templates

Here are some updates to get you rolling with angular-rails-templates.

- Cleaned up the custom haml/slim pipeline config
- enable [haml "ugly" mode](http://haml.info/docs/yardoc/Haml/Options.html#ugly-instance_method)
- updated `templateUrl`s (search&replace)
- updated `ng-include`s (search&replace)

The welcome page loads, and there are no GET requests for `*.html` files (all the templates are in `*.js` files)

Enjoy!
