This patch allows admin, or players with the chat_privs power, to change 
their name that is used on a channel. This can be useful for Dark admin who
still want to help out on a channel, but want to remain in the shadows.

To set your cname, simply set the attribute CNAME_<CHANNEL NAME> on yourself.

So to set a cname for the 'Admin' channel: &CNAME_ADMIN me=The MUSH God

NB: This also includes the addition of ANSI to the channel_broadcast. If
you already have colorized or changed this, then you will have to manually
patch the relevant code.
