* USERHOST now supports multiple (up to 5) arguments as per RFC1459.

* Allow servers to dynamically connect via a network PASS command for QWK auth.
* Introduced new N:Line flags because of this: 'w' defines the local QWK-master
  for forwarding PASS messages to, and 'k' is used for defining which N:Lines
  should have their passwords checked by the QWK-master uplink.
* WHO now supports a Bahamut-style complex searching syntax.  If the user
  doesn't use the syntax, we do more intelligent searching based on the
  information passed to us.
* Allow opers to see all channels that a user is on via WHOIS.
--- Thus, ircd.js is now over 150k in size, 5000+ lines of code.
