Added files for running in a production environment. Closes #66

Dockerfile defines the docker instance to run under.
Maekfile includes handy shortcuts for building and starting the Container "correctly"
nginx.conf contains config for the nginx instance inside the container.
updated requirements.txt to include gunicorn for running the app inside the container.
supervisord.conf is the config file for supervisord which loads the app and nginx inside the Container.

Better documentation about how all this works to follow.  Opening issue #81
