[Uml-devel] Added Copy&Paste between several instances of uml

[Gustavo Madrigal]

I just added Copy&Paste support to the cvs plus Multiple ListView Item 
Drag&Drop

UML now uses QT's global clipboard, this is done through the CUMLDrag class 
(derived from QDragObject). Also this class is used for multiple item 
Drag&Drop. This class also makes it posible to implement drag&drop between 
two instances of uml.

Also I would like to support folders inside folders, I already have some work 
on it but I think I will need to modify the file version (because of a change 
in mylistview's serialize function). Anyway, that change is partially on the 
cvs, so please check MYListView::serialize5 and let me know what you think 
about it.

I have 3 copy&paste cases missing:

	1- partial diagram selection copy&paste: Right now, copy&paste only works 
with items selected from the ListView.
	2- copy of operations & attributes to paste them into a specific class
	3- Add a special copy option under the Edit Menu to provide the old png 
behavior to the general clipboard


Thanks,
Gustavo
