Title: Add a --print-all-matched option.

The default behavior, to not print any matched lines, is unchanged.

This is useful to, for instance, process existing logfiles on a server/service new to fail2ban, to study what fail2ban would have triggered on and see if any tuning is needed to avoid false-positives prior to going live.
