	A #DbusmenuServer is the object that represents the local
	tree of #DbusmenuMenuitem objects on DBus.  It watches the
	various signals that those objects emit and correctly
	represents them across DBus to a #DbusmenuClient so that
	the same tree can be maintained in another process.

	The server needs to have the root set of #DbusmenuMenuitem
	objects set via #dbusmenu_server_set_root but it will query
	all of the objects in that tree automatically.  After setting
	the root there should be no other maintence required by
	users of the server class.
