404 on whats-new page.

If you visit the current fontawesome.io website and click twice on the whats-new page you'll be redirected to the Url http://fontawesome.io/whats-new/whats-new/ which doesn't exist.

This is due to the last commit b331a9a1c5d5fb1260de2f702623e26ac8e343dd where everything from the root directory of the gh-pages repository was copied into the whats-new directory.

With this change the default index.html in the whats-new directory was overwritten and because of this you'll see the homepage on http://fontawesome.io/whats-new/ and not the whats-new page.

Please ignore this pull request if this is a ongoing process which hasn't finished but it seems the website has been this way for 4 days. Also feel free to implement the change yourself.
