awesome stuff!

I just want to note, before this PR can be merged, we should address that the JS scaffold code is not adjusted for use with playbook yet, and I'm thinking, isn't this likely to break that?

[maackle]

@Connoropolous I guess as long as the npm package is published, the scaffold will also be fine, because the scaffold is just importing from npm anyway. When we change the scaffold to use diorama, that will mark the official switch/deprecation, but people are still free to use whichever test runner they want.

Given #1512 has been created and @maackle has committed to it, I'm good.
