Identifying via SASL

[Tehnix]

To connect to Freenode from an AWS instance, you need to identify via SASL. Is this supported currently, or would it be something that would be fairly trivial to add?

Actually, because of the way you just parse all options into JSON, it is already supported, just not documented.

From http://node-irc.readthedocs.io/en/latest/API.html#client you can see the options you need. My What I do string ended up looking like,

{
     "server": "irc.freenode.net", 
     "port": 6697, 
     "userName": "NICKNAME", 
     "nsPassword": "PASSWORD", 
     "sasl": true, 
     "nick": "NICKNAME",
     "password": "PASSWORD", 
     "realName": "MY REAL NAME", 
     "secure": true 
}

This should probably be documented. I'll add a PR.
