Remove stops_event_propagation from Window, since it's broken.

Changes it to be implemented by the Aura client, via a new interface EventClient.
The client can determine whether or not a given window and its subtree can receive events.
I also cleaned up the way screen locking is entered/exited via the delegate, and some stuff in ash/shell.
