* Written by Om <om@inspircd.org>, April 2005.
* Based on m_exception, which was originally based on m_chanprotect and m_silence
*
* The +I channel mode takes a nick!ident@host, glob patterns allowed,
* and if a user matches an entry on the +I list then they can join the channel,
* ignoring if +i is set on the channel
* Now supports CIDR and IP addresses -- Brain
