This patch begins the transition away from the global menu towards per-window menus instead. The global menu looks neat, but has always felt clunky, and there are a number of usability problems with it, especially in programs with multiple windows. You can now call GUI::Window::set_menubar() to add a menubar to your window. It will be specific to that one window only.
