Once again, my attempt to use git submodules didn't really work out. So I switched to pulling the repos via a gulp script.

I'm working on adding back and spine generation to my Fedran covers with a single source of truth. So, now its pulling the Git repos of all published books in based on the contents of another repo (fedran-data). Because I love automating something I do twice a year. :)

Actually, the "twice a year" is why I'm doing it. I keep forgetting steps.
