Docker and Lint additions

Created by: deyvidm

This update adds a Docker config!

Just clone the repo, run docker-compose up wait until the node logs say "Listening on port 3000" and visit localhost:3000

I also configured mounted volumes, so you shouldn't need to restart/rebuild the docker containers/images to see live code updates. The images would need to be rebuilt if you make config changes, but if you're doing that, I assume you already know how to operate Docker.
