Ember.ObjectController (and Ember.ArrayController) will be deprecated in
Ember 1.11 (and removed from core in Ember 2.0). The reasoning is
detailed in the Ember 2.0 RFC.
This PR does the following:
* Updates templates/controllers/views to explicitly reference model
properties (instead of relying on proxying behavior).
* Clearly delineate where certain properties are being set or retrieved
from (for example it was not clear exactly where `scratch` and
`titleScratch` were stored).
* Remove usage of `Ember.ObjectController`.
* Add JSCS rule to prevent future PR's from adding regressions.
