ASSP Filter Update

Added/Updated detection of:

* RelayAttempt (Scanners looking for open relays, drop to reduce attack surface)
* Auth error (Brute Force attempts, drop to reduce attack surface)
* Too frequent connections (Seen when attempting to deliver SPAM or Brute Force, drop to reduce server load)

Regex lines 12-14 are untested with newest release of ASSP. I personally have not seen anything in my logs that is caught by the Regex (For ASSP1?). 

ASSP Homepage has been down for a while, falling back the Sourceforge project page.

Fixed spelling

I recommend setting the ban time for ASSP to 2+ hours.  
move new (and remove old probably after verifying they are there too) examples into fail2ban/tests/files/logs/assp with corresponding failJSON entries
