Update documentation

[juherr]

https://github.com/dwdyer/uncommons.org/tree/master/reportng

I think GitHub page with a custom host (http://reportng.testng.org) should be enough

[juherr]

Done, but the documentation should be updated (link, date, ...)

http://testng-team.github.io/reportng

@juherr : Just curious to know, how did you manage to do this?

[juherr]

It's a github feature. Follow the link I provided.
Here, I choose to use the docs folder but you have some other possibilities.

@juherr - Before putting in the documentation into README.md I tried to fiddle around with the gh-pages part.. but for some reason the end-point that Github was generating was always routing me to testng.org/reportng and i was hitting a page not found error. How did you fix that part ?
