Newer version available

[Germs2004]

Is there a way to run the latest version of the private server using your Docker image? I seem to be stuck at 4.0.5 even though it appears 4.1.5 is available: https://github.com/screeps/screeps/blob/master/package.json.

If it's just a matter of updating the SCREEPS_VERSION variable in the Dockerfile, then I could do a pull request if you want. But it seems there must be another step to get DockerHub to rebuild the image there, right?

Even better, is it possible to just remove the hard-coded version number so that it will always use the latest available version when it runs?

Thank you
