Subject: Match id names case-insensitively

This fixes the case where an IRCd does not normalize channel names,
e.g. PRIVMSG #TEST is relayed as-is, rather than as #test or whatever
the canonical casing of the channel name is. It also fixes the case
of opening a query window with incorrect case, e.g. /query nickserv.

However, this solution is only completely correct when
CASEMAPPING=ascii.[1] I do not think the extra mappings of
CASEMAPPING=rfc1459 are relevant enough to justify adding the code
to handle it.
