Configure for Heroku

- Rather than following the instructions on the Phoenix website (http://www.phoenixframework.org/docs/heroku) we opted
  for setting up an app.json file and used the Deploy button to build the dyno
- Note the references to prod.secret.exs have been removed since these files will not be present
- All secrets for production will be set via environment variables
- The phoenix_static_buildpack.config needed settings for the umbrella app and to handle Phoenix 1.3
