listview R5

[Mike McCormack]

Hi Dimi,

It appears we need to duplicate the selected items DPA when doing 
RemoveAllSelections because some applications change on 
LVN_ITEMCHANGED/LVN_ITEMCHANGING notifications.

This applies after Dimi's listview R5 patch.

Mike


ChangeLog:
* duplicate Selected items list in LISTVIEW_RemoveAllSelections to 
prevent infinite loops
