Optimized layout of Cast Activity; removed landscape layout.
Made isFeatureEnabled() public
Clearing the context sets it to the application context instead of null
to avoid a NullPointerException when clearing the notification after
disconnecting from the Cast player.
Added CastActivity as a parent class with VideoCastManager lifecycle
callbacks and proper volume control. It also provides a default Cast
action view in the Action Bar that can be optionally overridden.
