This only changes the script-layer API, but keeps the std::string host in the C++ layer's ServerOptions. Mostly because the ixwebsocket library takes host as std::string. Also, maybe at some point we'd want to support something scheme-based like unix:///var/run/zeek.sock and placing that in a string could not be totally wrong. Add tests for IPV6, too.
