Support RLOGIN protocol

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';
```
