This patch replaces the verbose and kernel-quiet runtime options with a (hopefully) more useful quiet and silent modes of operation. By default Finit progressively shows all services it starts at boot, but when boot has completed and services are started/restarted Finit prints nothing. If `--disable-quiet` is given all started/restared/stoppping messages are shown even after boot. However, if `--enable-silent` is given Finit is completely silent even at boot, no progress is shown, until the first service is started, which on most systems is login.
