W3.org validator plugin, validate your websites with Ultros from irc!

This plugin communicates with [validator.w3.org](http://validator.w3.org/), reading it's headers for status, errors, warnings, and recursion.
Documentation: http://validator.w3.org/docs/api.html

A document can pass validation if it has no errors.

This plugin introduces one command, with two aliases:
`w3validate [url] [...]`, aliased to `validate` and `valid`.  
You can check up to three URIs at a time, with a minimum requirement of one URI. The bot will notify you if you are requesting too many URIs to be checked with a notice. And then look up the first three requested URIs.  
You need not specify entire urls, for example, `ultros.io` works as well as `http://ultros.io` or `http://www.ultros.io`. Should an URI be invalid, then the API will return an `abort` status error.
