Subject: Remove option to disable ipv6

It has been default for a while, is the only tested option,
and will only get more common.

-	A note about net_resolve and lookupd:
-
-	Many IRC networks rely on round-robin DNS for load balancing, rotating the list
-	of IP address on each query. However, this method breaks when DNS queries are
-	cached. Mac OS X and Darwin handle DNS lookups through the lookupd daemon, which
-	caches queries in its default configuration: thus, if we always pick the first
-	address, we will be stuck with the same host (which might be down!) until the
-	TTL reaches 0 or lookupd is reset (typically, at reboot). Therefore, we need to
-	pick a random address from the result list, instead of always using the first.
