(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)"
