This commit makes it possible to override settings during tests, by switching capsulflask/__init__.py to a "create_app" pattern, and using `dotenv_values` instead of `load_dotenv`. The create_app() method returns a Flask app instance, to give more control over when to initialise the app. This allows setting environment variables in test files. Then, use dotenv_values to override loaded .env variables with ones from the environment, so that tests can set `POSTGRES_CONNECTION_PARAMETERS` and `SPOKE_MODEL` (possibly others in future..). Inital tests for the "landing" pages, and login / activation, are included.
