Unknown CTCP queries and replies don't work
Currently, CTCP replies other than PING and VERSION are reported to the server status window as "Received unknown CTCP BLAH by nick!user@host". It also seems, at least from what I gather from #795, that unknown CTCP queries only send the type name of the query, but not any parameters that follow it.
It would be handy if unknown CTCP replies at least displayed as replies, not queries, and also if they would display the data included in the reply. That way, the CTCP TIME and FINGER queries built into the client's nick list context menus would actually be useful.
