William Pitcock 7e1bb8ad0d Proper channel mode classification. Fixes existing ad hoc
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.
