Improved the gesture api.

Added a new widget attribute Qt::WA_DontUseStandardGestures that disables all
implicit gestures (i.e. gestures that are automatically enabled by Qt itself).

This change also changes the way gestures are handled on
QAbstractScrollArea-based widgets on Windows - the gestures are supposed to be
created on the viewport widget.
