This allows for reproducible builds.
Also, fix Dockerfile to first build and then run tests and a typo in the entrypoint.
Thanks @BenHall for reporting the issue with the Docker build!
1. Bump Node version to 6.9 - the latest LTS
2. Include the `cpio` binary, used during building
3. Ignore node_modules and .git directories for faster builds
4. Run the tests and build during the image build, to make sure the image is not built if these break
5. Make npm run dev the default command
6. Add an entrypoint to automatically install Node modules if they do nott exist
