Changed the container register in the helper to account for:
https://github.com/emberjs/data/pull/1653/files

Promises are now instantiated and passed an empty anonymous function:
https://github.com/emberjs/ember.js/commit/ea2d13b7e793435b208bdc4286c08673af03c153

Also Switched over to Bower components on the test page to make things a

Travi now needs to run `bower install` before running the tests.
Updated README for beta.6 and bower.
