Removed "scope.lookupvar" calls
Added logging to *all* protocols

I thought this was the default but it is not, so it’s now explicitly
set.
Added firewall logging rules before PSAD install

This prevents PSAD from sending an email complaining about the lack of
logging on it’s first run.
Added IPv6 logging
Changed default configuration settings
Config template handles arbitrary arrays better
Clarified blocking and PSAD usage
Updated version and changelog
