Build a docker image for ansible-artimed

[mvdbeek]

This one should be low-priority, but a simple Dockerfile with ansible would be enough
to clone this repo and setup the artimed instance. Nice for quick bugfixing :)

FROM ubuntu/14.04

RUN apt-get update && apt-get install build-essentials ansible
ADD galaxy.yml /galaxy.yml
RUN ansible-playbook galaxy.yml

Obvisouly I didn't test this, but it should be very easy with good ansible roles and playbooks :).
