Modifications after the api review by Brad.

Gesture types are now separated to internal ones, which are listed as
enums (though they might be converted to strings internally), and
third party gestures which are referenced by strings.

From now on QGesture objects derive from QObject, which means third
party gesture recognizer developers can use QObjects property system
to store custom data inside QGesture without need to subclass it.

Some functions were renamed to show their purpose more clear.
