Let's keep it easy and don't reopen/close package windows in desktop 
change. Package is something like an independent project so let's handle 
them the same as editor windows.

BTW. I heard some rumours that project groups should be supported at 
some point (?) - the same modern Delphi has. If it is so, the package 
editor will be deleted anyway and replaced by the project group window.
