Upgrade to ruby 2.1.2
Remove .ruby-version.

We're now using Docker rather than rbenv.
Remove Figaro.

Just use environment variables directly. Like a boss!
Remove deploy directory.

Because we're going to try deploying with Docker.
Add db/production directory.

Where we'll link the production database as a Docker volume.
Turn on serve_static_assets in production.

Until I figure out how to get nginx to do it when deploying with docker.
Add Dockerfile.
