Move logic from QSCarrierGroup into Controller.

This removes the injection into the QSCarrierGroup view
and moves it into an associated controller instead.

Controllers are added for QSCarrierGroup, QSContainer,
and QuickStatusBarHeader, though only QSCarrierGroup does
any heavy lifting at the moment. The other controllers are
parent controllers that are needed to ensure everything is
cleanly initialized when the view is inflated.
