We can't safely support IPv6 with our default blacklist since even hosts on the intranet will usually have globally-routable addresses. Add a flag to disable IPv6 support and enable it by default. Since we handle this in `resolve()` by filtering IPv6 addresses and raising a `UnknownHostException` when all addresses were IPv6 we maintain API compatibility with previous versions of SafeURL.
