Title: Use a timeout to abort long uneventful drag operations.

This is an attempt to work around issue #731, by setting a timeout that will cancel any drag-and-drop operation that does not produce any events in five seconds. It works fine in my testing, apart from an issue with the window list not being fully responsive for a few seconds after a cancelled drop - hopefully somebody with more insight in DND or the window-list applet can fix that.
