This patch adds support for touch scrolling in Dolphin using QScroller, with touch events sharing some functions with mouse events to behave like clicks. Rubberbands do not trigger during touch scrolling. To prevent accidental item activation during touch scrolling, I check if there was a touch update event with a touch move emitted in between a touch begin and a touch end event, in which case I prevent item activation from happening. Also added the QScroller gesture to the information panel (which is kinda wip right now due to issues).
