Override style->realize/ style->unrealize, so that GTK+ doesn't

        * modules/engines/ms-windows/msw_style.c: Override style->realize/
        style->unrealize, so that GTK+ doesn't automatically attempt to apply
        shading to the GC colors, causing a mismatch with the Win32 native
        colors. Problem found by (and suggested solution by) "Cosmic Integer"
