Replace verbose and kernel quiet modes with silent and quiet

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.
