Add NICK :)
Add note about matchirc use
Add irccmp, casecmp, and matchcmp for fancier string comparison
Merge branch 'master' of git://github.com/Elizacat/ircd-micro
Use irccmp in NICK, and ignore changes to identical nicks.

And add legacy behavior ;)
Few minor fixes to NICK and friends

  o  Cut nickname changes at MAXNICKLEN, so that we are only looking at
     the form of their nick they will actually end up with

  o  Add ` as a valid nickname character

  o  Invert interpretation of irccmp's return value. When I changed this
     from matchirc, I forgot to account for the fact that irccmp works
     like strcmp, rather than like a matcher.
