Answer WHOIS IDLE for our pseudo-clients

A two-parameter WHOIS (/whois x x — what mIRC sends when you double-click a nick,
to fetch idle time) routes the query to the target's server. For a service that
server is echo, which was dropping the resulting IDLE request as an unknown
command, so the WHOIS produced no output at all: InspIRCd only emits the whois
numerics once the IDLE reply arrives (m_spanningtree/idle.cpp), so no reply meant
total silence.

Handle the inbound IDLE request and answer it for our own services and bots:
":<target> IDLE <requester> <signon> <idle>", signon = burst time, idle 0 (a
pseudo-client is always active). A routed WHOIS of NickServ/ChanServ/etc. now
completes.
