Ember1.0 cleanup
Upgraded to ember-data 1.0 beta 3
Updated the embedded add rating integration test
improve getHasManyAttributeName algorithm

if some of the records are already loaded, then the array of ids sent to `getHasManyAttributeName` will not directly match the list of ids for the relationship.

This updates the `getHasManyAttributeName` method to match attributes that at least have the requested ids present instead of requiring a direct match.
