Docker image for 7 Days to Die Dedicated Server

Docker the image

1. Ensure /config is mounted inside the runtime, ie -v /opt/7dtd/:/config
2. First time it runs, it populates a sample serverconfig.xml then exits, giving you time to modify it to your needs.
3. Map data gets symlinked into /config/Saves/

Update automation

IFTTT monitors the RSS feed of the games news, and will trigger a dockerhub rebuild of the image, pulling down a new version of the game. This is sub-optimal as any time they announce a sale, it will rebuild.
