Allow commiting and then reusing a QTouchEventSequence for testing.

This method allows calls to stationary() to automatically remember
the previous position for a given touch point id. Example usage:

QTouchEventSequence sequence = QTest::touchEvent(&window);
sequence.press(0, QPoint(10,10)).commit();
sequence.stationary(0).press(1, QPoint(40,10)).commit();
