commit e46cf64cc1e3bf21060df1d1125502277d035170
from: Alexander Barton <alex@barton.de>
date: Wed Sep 30 14:00:06 2009 UTC

New "module" op.c/op.h for IRC operator related functions

The new "module" op.c is used to implement functions related to IRC Ops.
At the moment, these two functions are available:

 - Op_Check() to check for a valid IRC Op, and
 - Op_NoPrivileges() to generate "permission denied" messages.
