Subject: (svn r11551) -Codechange: Introduction of widget control members on
 struct Window.  These "new" members have the exact same functionalities as
 their pure functions "genitors" Ex: "Window::SetWidgetLoweredState(byte
 widget_index, bool lowered_stat)"  is the member corresponding to
 "SetWindowWidgetLoweredState(Window *w, byte widget_index, bool
 lowered_stat)"
