Add jasmine tests to Travis

[gemfarmer]

I just noticed that the auctions/winners page is broken in prod, likely because the Jasmine tests aren't configured in Travis!

As a corollary to this Travis issue, all code should be updated so that the Jasmine tests pass. This will likely just mean renaming some methods in the JS, as there were several recent renaming PRs.
