Background from Option Window is not skinable [#7607]

[DreadM]

Background from Option window is not skin able (ToolWindow /Client),
every skin use the same background !
After reduce from aero use in menus this background should be skinnable like in MM3

Screenshot shows MM3 and MM4 with same Background definition !
