Paul Melnikow fa5309400d PaaS, CI, and production-friendly config (#2626)
This implements the configuration mechanism I described in #2621. The heavy lifting is delegated to [node-config](https://github.com/lorenwest/node-config) with a minor assist from [dotenv](https://github.com/motdotla/dotenv).

`private/secret.json` has been replaced with environment variables and/or `config/local.yml`. See `doc/server-secrets.md`.

// That way most of the current static methods could become instance methods,
// thereby gaining access to the injected config.
