Update to latest Ember-Data and Ember.js from GitHub master
Replace deprecated Ember.empty with Ember.isEmpty
Upgrade QUnit to v1.10.0
Add support for testem test library

Tests can now be run via testem command, as described here: https://github.com/airportyh/testem
Add test case for newly created parent for a hasMany relationship
Cleanup CouchDBAdapter
Set context of ajax call to the adapter by default
Guarantee clean ajax assertions state before each test
Add utility method `view` which accesses a CouchDB view

The findAll method on the adapter has been refactor so it uses the introduced `view` method. Specifying a custom "get all models of type X" can now be implemented by overwriting findAll using the adapters' `view` method.
