    applet: add helper function for partly folded menus
    
    helper function adds a GList* of menu items to a GtkMenu in a way
    that displays most important N menu items on the top level and
    fold the rest to a submenu
    
    The algorithm first sorts the list using the prio_cmp_func to create
    a list of most N important items; this list is again sorted using
    the generic_cmp_func before being added to the top level of the menu;
    all items not among the N most important ones are added to a submenu
    passed as parameter to the menu; the submenu items are sorted using
    the generic_cmp_func.
