Add docker support

[tekkub]

👋 @maddox

So I added docker support for you. I included an example docker-compose.yml file too. If you end up pushing an image up to docker hub, you'll want to change the build: . line to image: maddox/dasher.

One caveat: since the docker image runs as root, I skipped your setup script and instead ran the button finder directly:

docker run -it --rm --privileged --net=host tekkub/dasher \
  node node_modules/node-dash-button/bin/findbutton

I know literally nothing about Docker, lol. So I guess this is all good? @jnewland?

Also, I just created a docker repo here: https://hub.docker.com/r/jonmaddox/dasher/

Could we point it at this? This pull on another of my repos has something regarding this.

I was thinking about dockerizing this, and was excited to see this PR. Is there anything that can be done to help get it into dockerhub?

Is --privileged really necessary?
I'm running clemenstyp/dasher-docker on my system without it and it is working fine.

[tekkub]

You are indeed correct!

@maddox I have no experience with docker hub myself, I've only really been using docker for my own private things. ¯\_(ツ)_/¯

I have dockerhub experience! :) It's really easy to link a dockerhub repo with a github repo. I did it myself as a proof of concept with this github repo: https://hub.docker.com/r/americanwookie/rpi3-distribution/. Docker makes it really easy if your comfortable with linking your dockerhub account to your github account and giving docker several permissions.
