+	* MenuBackend.C (expand): move from Menu to MenuBackend; pass a
+	Menu as first parameter. Now, this calls itself recursively to
+	expand a whole tree (this will be useful for TOC handling)
+
+	* MenuBackend.h (submenuname): returns the name of the submenu.
+	(submenu): returns the submenu itself, provided it has been
+	created by MenuBackend::expand
