MSN (IRC8) compatible connection script

Requirements

  • AdiIRC-first - Works with both mIRC and AdiIRC
  • Native GateKeeper / GateKeeperPassport Authentication
  • Support WHISPER (and converts WHISPER to & from PRIVMSG)
  • Convert IRC8 JOIN to IRC JOIN
  • Support MODE on IRC8 JOIN (+v/o/q)
  • Convert IRC8 NAMES to IRC NAMES

Nice to haves

  • Convert styled PRIVMSG to normal PRIVMSG
  • Supports CTCP "ERR NOUSERWHISPER".
  • Convert AWAY to IRCv3 AWAY (if it does something in clients)
  • Don't default to IRC8

Known Issues

  • Auth doesn't always work with AdiIRC (probably due to UTF8 quirks)
