  * irc: Improve the parsing
  
  Recognize commands case insensitive: the RFCs are not very concise about
  this and I don't know about clients sending commands in lower case but
  just in case and it won't hurt
  
  Line terminator: according RFCs should be \r\n but some clients only
  send \n, I was confused about this but the parser must be robust and
  now any combination of \r and \n is recognized
