Expose some JavaScript resource models and make them more useful.
Review Request #5692 — Created April 9, 2014 and submitted
This moves Repository and associated models into the 'common' bundle, so
that they can be used outside the New Review Request page.It also adds rspNamespace fields to Repository and ReviewGroup, allowing
them to successfully parse payloads from the server.
Made use of both Repository and ReviewGroup, and saw it successfully handle
parsing the payloads.
