Currently, any number of menubars can be plugged in and out of a window. This is unnecessary complexity, since we only need one menubar on a window. This commit removes most of the logic for dynamically attaching and detaching menubars and makes one menubar always available. The menubar is only considered existent if it has at least a single menu in it (in other words, an empty menubar will not be shown). This commit additionally fixes a bug wherein menus added after a menubar has been attached would not have their rects properly setup, and would therefore appear glitched out on the top left corner of the menubar.
