Moved "Authentication attempt for unknown user" to wordpress-soft.conf
The hard filter is intended catch things that are never good, and to ban the IP immediately.

When I first added the rule to catch login attempts with an unknown username, I put it in the hard filter as that’s what made sense at the time; back then, WP fail2ban users didn't get their username wrong.

In v5 I’ve moved it to the soft filter as that’s what makes sense now - things change.

There should now be no reason not to have maxretry = 1 in your wordpress-hard jail.

Moved "extra" Comment messages to wordpress-soft.conf
The "comment-extra" messages were a successful experiment.

By standardising the messages they've been condensed to a single rule; with essentially no performance penalty, they can now be included in the the soft filter.
