Support RLOGIN protocol

[tracker1]

Would be cool to support RLOGIN as a protocol for synchronet...

   wsProtocol : "rlogin:user:pass:info",

Where it's a raw/plain connection, but on connection, the info after rlogin: is sent null delimited over the port at the top of the connection, from there, it works like a raw socket connection.

   "rlogin:user:pass:info".split(':').splice(1).join('\x00') + '\x00';
