- new modules implementing script callable blacklist functions:

   blst_add([timeout]) - adds the message source to the blacklist
   blst_add_retry_after(min, max) - adds the message source to the blacklist
                         using the Retry-After header value as the timeout
                         value (if not present it returns false)
   blst_del() - deletes the message source from the blacklist
   blst_is_blacklisted() - returns true if the message source is in the
                           blacklist
   (for more info see the module docs)
