making ouija use config.py for user with docker

This pull request is to make ouija work with Docker, which I have built over in https://github.com/jamonation/ouija_docker (based on https://bugzilla.mozilla.org/show_bug.cgi?id=1010465)

This repository is a git submodule inside the docker container so that it can remain as a standalone python virtualenv, in addition to working inside Docker.

Testing and feedback are much appreciated!
This should stay False in the main ouija repo so I don't accidentally deploy this to production with debug enabled.
