uxtheme.dll

[Steven Edwards]

This is very kickass dude. I think this is the right method of
supporting themes for WINE. KDE can already do GTK themes with a little
bit of tweaking so it will support both Linux Desktops and GTK themes
are now supported under Windows with GTK-Win32 so maybe we can even use
this in ReactOS when its ready. 

Thanks
Steven
