Fix navbar to work with CloudFront

CloudFront will not automatically serve the index.html in a "directory".
Adding index.html the paths is easier than automating the creation of an
object named like a directory (basically, cp projects/index.html
projects for example) and is cheaper than trying to fix this with
Lambda@Edge.
