:nth not supported

[chr4ss1]

Hey, nice work. I like this project more than HtmlAgilityPack, I am still scarred by xPath.

I was using latest CsQuery, and tried to use query which is a long of the lines:

dom["input[type=email]:nth(2)"] which blew up, but is supported by jQuery. I ended up going with dom["input[type=email]"][1], which works, but would be cool to have first syntax aswell.
