Log message:

Finally tracked down why ERROR messages from servers we're connecting to
aren't being saved: there was no handler for ERRORs from unregistered
clients!  Curiously enough, handlers.h had a declaration for one.  Anyway,
I added one, with a test for IsUserPort() so that ordinary users can't
abuse us (I hope...), and it now works fine.  Also removed an unused
variable found while trying to track down a bug that causes some servers
and users to not be sent in the BURST--I haven't yet tracked that bug down,
unfortunately.
