* Removes extraneous paragraph from docker documentation
It looks like this line was intended to go somewhere else, but got
erroneously bumped into the `Restart` section.
* Adds instructions to expose devices when deploying under docker
* Adds info about `docker-compose.yml` configuration to docker deployments
The docker command is pretty complicated and doesn't support automated
restarts. I think most users with want to use `docker-compose` (or
`docker swarm`) to deploy.
