Added .nojekyll to disable github jekyll.
* This is done in order to enable symlinks.
Added symlink current to 14.3 doc.
Added index pages to avoid 404.
* http://www.go.cd/documentation and http://www.go.cd/documentation/user don't result in 404 anymore. They provide proper information to proceed further.
