* Fix freeing of module parameters (they should NOT be freed)

* Add minimum hash length to check with fuzzy module as well as whitelisting for fuzzy checks:
  min_length = "300"; <- messages with more than 300 characters would be checked with fuzzy check
  whitelist = "http://somehost/somefile"; <- ip addresses whitelisted
* Extend comments about module options for comfortable usage
