* Allow DATABASE_URL to contain custom MySQL ports for docker-entrypoint.sh
* Drop WORKERS count to 1 to avoid dealing with Flask-SocketIO sticky sessions
* Stop gunicorn from logging to `LOG_FOLDER` in docker without explicit opt-in
* Re-add the `LOG_FOLDER` envvar to docker-compose so we don't try to write to the read-only host
* Add `ACCESS_LOG` and `ERROR_LOG` envvars to docker to specify where gunicorn will log to
* docker-compose improvements
* Use gevent gunicorn workers
* Makes logs easier to access
* Customization of the logs location
* Improve secret key generation & only generate secret keys if one isn't defined (Closes#123)
* Install requirements required by plugins
CTFd creates the database instead of the docker-compose files which allows us to control encoding. Also adds a test for registering with a unicode team name.
