I've decided it may be easier to consolidate my Mac-specific roles (homebrew, mas, and the like) into one collection, where all my Mac-specific testing can also be optimized.

I'd also like to move the dock management stuff in this playbook out to that role and clean it up a bit, now that I've had a chance to really wrap my brain around dockutil.

And probably also move the sublime-text.yml task and associated vars into a separate role there too.
