Django-spinproject

* pytest support 'cause you don't want to waste time on setting that up (give it a try: `script/test`);
* Always call the settings directory `main` 'cause that's the only way to keep people sane when switching projects;
* GitLab CI config generator 'cause you don't want to write one yourself;
* flake8 isn't expected to be installed on your host system anymore.

* `.gitignore` to keep your VCS clean;
* `.dockerignore` to keep your Docker images clean;
* `make clean` to get rid of `__pycache__` files when you need that;
* No need to install `django-postgres-readonly` anymore.
