[PySide] re-implementing setDown() for custom button

[Srini Kommoori]

Thats great.

One thing I observed is: for your custom button, if you want a nice/native
copy icon to appear - set following in your dragEnterEvent(I would prefer
to do have dragMoveEvent)

event.setDropAction(QtCore.Qt.CopyAction)
event.accept()
