ToDo-List:

	- show error messages
	- add a nice output window for scp (design done)
	- browse target host tree (scp)

Things I don't know how to handle by now:

	- remember window position
	- check normalize code in clist/ctree d&d-receive
	- with window type WINDOW_DIALOG window doesn't get d&d
	  signals when hiding & showing the window any more
