OperServ: CBAN — ban a channel name

Browse source 
CBAN ADD <#channel-glob> <reason> / DEL / LIST blocks users from creating
or joining a matching channel (m_cban is loaded). Another kind ("CBAN")
in the generalized X-line handler with a channel-mask normalizer; the
too-wide guard now ignores a leading channel prefix so #* is refused.
