Introduce TapHandler
Device-agnostic tap/click detection. Also detect whether the taps or clicks occur close enough together in both time and space to be considered part of a multi-tap gesture. Change-Id: I41a378feea3340b9f0409118273746a289641d6c Reviewed-by: Jan Arve Sæther <jan-arve.saether@qt.io>
