change the way ControlProtocols (control surfaces) are notified and handle Stripable selection changes

The Editor continues to notify them, but via a direct call to ControlProtocolManager, not a signal.
The CP Manager calls the ControlProtocol static method to set up static data structures holding
selection info for all surfaces and then notifies each surface/protocol that selection has changed.
