- Update MotionPauseListener to have 2 methods: the existing
onMotionPauseChanged(isPaused) and onMotionPauseDetected()
- onMotionPauseDetected is the default as most listeners only
care about the first detected pause
- AbsSwipeUpHandler still listens to pause changes, to help
determine the end target at the end of the gesture
