Added QGraphicsSceneGestureEvent that extends plain QGestureEvent by
providing some additional info (like a widget that received a gesture - for coordinates conversions).

+ QGraphicsSceneGestureEvent extends information provided by
+ QGestureEvent by adding some convenience functions like

+ mapToItem() for converting positions of the gesture into
+ QGraphicsScene and QGraphicsItem coordinate system respectively.
