RFC: Switch repo to Action (maintained, updated version of Meatier)

[mattkrick]

TL;DR do you want a Meatier that is updated at the cost of being slightly more opinionated?

Since I published Meatier, I got hired to basically build it into a legit marketable product. That product is open source & found here: https://github.com/ParabolInc/action/.

I don't have the time to backport all changes to Meatier, so what I'm proposing is replacing the current Meatier with Action as it currently is.

Pros:

• Up-to-date packages!
• CSS in JS!
• Popular example patterns like user presence, deploying to S3, DB migrations, react-driven emails, etc.
• You can still use it as a boilerplate-- just nuke server/graphql/models and universal/modules and you're set to make your own app!

Cons:

• Uses Auth0 (it's free to small apps) instead of a completely custom GraphQL auth solution
• ???

@devel-pa @wmertens you guys put in a LOT of hard work in your PRs to update Meatier & I feel like crap not having the time to fully test them out.
