Bram Matthys 51d30af3fd - Applied patch from k4be (#0003866) which introduces a new packet hook 
(HOOKTYPE_PACKET). Replacing the 'text to be sent' to a client is
  supported, which allows character(set) conversion in a module.
  Note that modifying an incoming message by the hook is not supported.
