paramnum - see example
  Returns all data starting from the end of the paramnum parameter. Hard to explain, here is an example.
  Example:"PRIVMSG cyndabot :kick foobar go away").getMessageParams(1) =>
  "go away"
  Kick is the num 0 parameter, foobar the 1 and go the 2.
  The 1 means that it will start from the end of the the num 1.
