Sets or unsets the menubar for windows of application.
This is a menubar in the traditional sense.
This can only be done in the primary instance of the application,
after it has been registered. GApplication::startup is a good place
to call this.
Depending on the desktop environment, this may appear at the top of
each window, or at the top of the screen. In some environments, if
both the application menu and the menubar are set, the application
menu will be presented as if it were the first item of the menubar.
Other environments treat the two as completely separate — for example,
the application menu may be rendered by the desktop shell while the
menubar (if set) remains in each individual window.
Use the base GActionMap interface to add actions, to respond to the
user selecting these menu items.
