More deets about goat

I am starting up a project and planning to use goat (there you have it, money where my mouth is), and in the spirit of new projects, I've been exploring it more, which reveals:

- goat deps will detect other .go.yaml files and handle them recursively
- there's a PR for goat gen but it's dead right now (perhaps I should revive it)

I was also reading an issue on godep that discussed some concerns about transitive dependencies, but I'll come back to that later if I feel like exploring it more.
