Merge pull request #56: Prefetch all files on clone

Will disable later when doing sparse clone. This speeds up our functional tests (and any clone we do for local testing). With the current count of functional tests, they run in 3-4 minutes instead of 5-7 minutes. As that list grows, this will be even more important.
