Add docker setup (#204)

* Initial docker experiment

* This works - for me.

* Fix env files

We will default to 8001, since the default port for bornhack-website is 8000.
The default db port is 5433.

* Update Dockerfile to install dev,test dependencies

Some dependencies from dev was not installed.

* Move docker compose environment stuff into compose.yml and restore .env.dist.
