Create controller for StatusBarWindowView.

This moves most of the logic out of the view and into
StatusBarWindowViewController. It is not beautiful, but
it is cleaner than before.

This removes the final call to Dependency.get(FalsingManager.class).

This also fixes a small, old bug in
StatusBarWindowView.onInterceptTouchEvent where the results
of calling hte super method were being unintentionally ingored.
(This bug would have been introduced nearly seven years ago.)
