Please update repo to work with latest ember and ember-data

[ricardogsilva]

Could you please update the ember and ember-data libs to the current versions? I'm trying to follow along, and stumbling into some errors. It would be nice to use this repo as a guide ;)
Thank you

I'll try to do it soon. The problem is that the latest ember.js includes the new router interface and still haven't had time to explore it.
