Hi,

This adds a configuration field to the home-shepherd to optionally invoke it
with --silent. See [1] for details. The option currently only actually works
as advertised when using the development branch of shepherd, for the current
version (v0.10.5) the --silent parameter is ignored.

I have set the default value to #f to not change the current behaviour.

For the documentation I am not perfectly happy with my description because the
behaviour is opposite of the description (Setting to #t causes no output to
stdout), maybe there is a better way to phrase this? Also is there a better way
to communicate that it only works when the auto-start? field is also #t?


Related: The daemonize? field is not documented and the accessor is not being
exported.
