[ENHANCEMENT] Update ember-qunit to 0.2.0.

[rwjblue]

The update to ember-qunit 0.2.0 has a few caveats but is largely compatible with 0.1.x. A few of the main changes are:

• Rewritten to be a thin wrapper around ember-test-helpers, which are now shared between ember-qunit and ember-mocha.
• Deprecated this.append() in favor of this.render() in moduleForComponent.
• setup callback no longer receives the container as its first argument. This requires a largely mechanical refactor to use this.container in the callback (instead of using the first argument).

Users that update ember-cli-qunit, but not ember-qunit will see no changes (ember-cli-qunit itself is compatible with both versions).
