[gnome-menus] Fold sorting into GMenuTreeFlags



commit d660a95756c99fe053ffd4fbaf523008868f5a67
Author: Colin Walters <walters verbum org>
Date:   Sun Apr 17 07:10:01 2011 -0400

    Fold sorting into GMenuTreeFlags
    
    There's only two sorts right now, and so we can make one the default
    and select the other with the flags.
    
    Drop the ability to set the sort at runtime; this never was compatible
    with the current GMenuTree caching, and also I'm trying to move
    GMenuTree towards being immutable.
