FreeBSD Port: py25-fail2ban-0.8.3_1

[Chris Jones]

Hello.

As you know, many people are now using PF on their FreeBSD servers. I've 
made some changes to make it work with PF, and I think they are worth 
including in the port by default.

I'm including the configuration needed to use Fail2Ban with PF on FreeBSD.

Basically, you make a table in PF, and add to the table as the 
'actionban' and remove the entry from the table as the 'actionunban'. 
Pretty simple.

You can easily see a list of banned addresses using:
sudo pfctl -t fail2ban -T show

Thanks for the port of this great utility!

- Chris
