Ember CLI addon conversion (Simpler approach)

This is a less earth-shattering alternative to #39. It preserves the existing build process to preserve compatibility people who are installing the library through bower. The primary drawback of this approach is that `ember init` won't be very useful, since it assumes a very different directory structure.

Should be. The bower package name changed from loader to loader.js at some point.
