[PATCH] Fix Ugly borders around undecorated windows in Gnome

[Matthew D'Asaro]

This is my first attempt at submitting a patch to WINE, so please excuse
me if I have broken any conventions or am going through the wrong
channel. As it currently stands, wine is setting the 'MWM_DECOR_BORDER'
hint on managed but undecorated windows, such as iTunes, or Winamp. This
does not cause problems in KDE, but in Gnome it puts a gray border
around such windows. Not setting this hint does not seem to cause
problems in KDE and fixes the problem in Gnome. A patch to do just that
is attached. Comments?
