channel mode classification which is required by RPL_MYINFO indicating arity,
and RPL_ISUPPORT indicating an enumerated class. The content of these replies
had previously been generated by hardcoded strings of some letters.
Channel modes require classification which corresponds to the
CHANMODES= data in RPL_ISUPPORT. Classes A,B,C can then be
listed in the unary column of RPL_MYINFO. cflag_add() is updated
for this. Additional cleanup of chmode.h and channel.h
circularity is also proffered within.

RPL_ADMINME is a response the client receives using the ADMIN command.
Charybdis used to implement a non-standard version of this.
The RFC 1459 standard [1] says in section "6.2 Command responses.":
256 RPL_ADMINME
"<server> :Administrative info"
This commit corrects the behavior to follow the standard.
