Updating more configuration directives because so much has changed since
the last release of ngircd.  Some of them default to "not for the
better."

Updated directive for server-server communications.  There's really no
good way to do an ad-hoc IRC network, we really need something that
works better for this sort of thing, so the best we can do is minimize
the potential damage and keep an eye out for gross failure modes so we
can jump on them as fast as possible.
