WindowServer+LibGfx: Show menus in windows! :^)

Browse source 
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.
