der richter 7e07e1a087 mac/apphub: migrate remaining events functionality to new AppHub 
add new app_bridge objc file for bridging between mpv core and app
functionality. replace old EventsResponder singleton with AppHub.

another step to clean up all App functionality and have one central
place for it.
