The --init option will also upgrade an already existing site and
is processed in non-interactive (batch) mode.
This is a rework of the automatic schema upgrade feature that was
introduced with de980a4ddd and is
reverted with this change. Running init is more generic and also
supports initialization of a new site on daemon start.
Besides automatic upgrade, this feature also makes developers work
more comfortable as it can eliminate running init as a separate
step before running the daemon.
