    schemas: Add 'avatar-directories' setting
    
    gnome-control-center and gnome-initial-setup uses the default faces dir
    for user avatar defined by $datadir/pixmaps/faces/ that's were the
    gnome-control-center install the faces images.
    
    This new setting will allow to change the default faces in both projects
    only changing this setting without the need to patch
    gnome-control-center.
