    data: set shell classic mode via env variable instead of command line
    
    Currently, we start gnome-shell in classic mode by passing
    --mode=classic to the gnome-shell command line. This --mode=classic
    gets stripped away when the session is saved, which breaks classic
    mode on subsequent login attempts.
    
    This commit changes the session file to set the
    GNOME_SHELL_SESSION_MODE environment variable instead.
