Title: Will/top scores fixups

* Enable caching for leaderboard (to increase page load speed)
* Fix the location of the "loading" step status for leaderboard.

I'm going to open a separate PR in edx-submissions to explicitly set the cache timeout, since I think it's set too high in production.

@stephensanchez Please review.
