[PATCH] small improvement for DnD

[Willem Rein Oudshoorn]

Target will be informed when we press modifier keys.
This gives applications like GWorkspace a change
of changing the default action.

Also, to protect against badly written clients, we only
attempt to drop when target and source and the user 
(with modifier keys) agree that something can be dropped.
This improves a fix of Fred Kiefer.

        * xgps/Source/SharedX/XGDragView.m ([XGDragView -_handleDrag:]): Now 
only
        deposit drop when source and target agree.
        ([XGDragView -_handleEventDuringDragging:theEvent]): send 
draggingUpdated event
        when user changes mask by pressing modifier keys.
