    Make session saving work a bit better
    
    Previously, the restart command hardcoded "mutter" as the binary name.
    This commit changes it to use g_get_prgname() which has a better chance
    of being correct (and it does fix session saving for gnome-shell).
    
    Now that mutter is a library, it might be more correct (but also
    much higher overhead) to add api for setting these things from
    the outside.
