iOS: Implement button press/release and motion notify.
We do this overriding touchesBegan, touchesEnded and touchesMoved methods
respectively. A long touch on a supported widget will generate a button 2
event, any other will generate a button 1.  Motion isn't supported without a
touch, so there will always be a button masked.
