Version 3.0.0

Breaking change

• The app user and group were renamed from 'app' (passenger-docker's default)
  to 'dora' in order to further eliminate confusion. Now there is only one
  directory named 'app', and that is the said directory in a Rails application.
  Important: If you relay e-mails into your dora container as described in
  README.md, you will need to adjust the paths in your mail server configuration
  files, e.g. master.cf if you use Postfix.

New

• Implemented basic status reporting.

Fixed

• rails-console.sh now invokes rails as the app user.
• Removed the erroneous server_name directive from the Nginx site configuration
  file.
