Updated docker-compose to working state. Removed reliance on traefik.toml

- New .env example with streamlined variable names
- Assumes https by default with http-to-http redirect enabled (Remove the redirect on line 25 to disable this)
- Assumes each domain(s) specified are different from one another, so that all parts can all be accessed from the same port (443).
- Forcibly disabled traefik on the db so that it won't try to get a certificate for it (I don't know why it does this)
- Set specific versions for Matomo (3) and Ghost (2) to avoid watchtower automatically making big upgrades

Still missing:
- The first time Ghost will fail to launch as MariaDB isn't ready right away. docker-compose got away with a health check. I might want to play with https://github.com/vishnubob/wait-for-it later
