[cheese] countdown: move rsvg_init and rsvg_term into main

    countdown: move rsvg_init and rsvg_term into main
    
    Initialize rsvg at startup and clean it up at exit.
    rsvg_term is particularly subtle as it calls xmlCleanupParser()
    triggering nasty crashes (e.g. with PulseAudio) with multithread
    applications.
    See http://0pointer.de/blog/projects/beware-of-rsvg-term.html for more
    info.
    Rsvg loading seems to work even without these functions so I'm not sure
    it's worth to keep them.
