Hi all!

I've been keeping an eye on Arionum for some time and was mining it with the Java miner. However I did find that ariocppminer has better performance so I decided to make a Docker image and upload it to DockerHub: https://hub.docker.com/r/nunoferro/ariocppminer

The only change I made, besides creating the Dockerfile, was to add and argument to set the workerID.
