    rhythmdb: use g_ascii_strtod to read the db version (bug #616636)
    
    We previously used sscanf(), which is (sometimes?) locale-aware, so in
    some locales, it was expecting a comma instead of a full stop as the
    decimal separator.  Misreading the version causes upgrade processing to
    be run on each startup, rather than just once, which messes up podcasts
    among other things.
