Whole project was broken and abandoned

Reworked the whole concept of the Dockerfile to make it work
Now it runs from the nginx server as the `app` user. The Readme file will require some more corrections, as I noticed after committing it, that it still refers to using port 3000. Reverse proxy has been tested as well and the logs are written with the proper forwarded IP address as the client. I thought I'd have this done days ago, but I got delayed several other projects things I'm working on.
