Add a DragHandler::translation property

This allows the application developer to get the translation of the
dragged pointer, and apply it in a custom way.
This should usually be combined with setting target to null.

This will for instance be needed when we want to drag QtLocations map,
where a map is dragged by specifying the geo location of the center of the
map.
The map2.qml example demonstrates this.
