Official docker image

[T-vK]

There are a few hollywood Docker images out there, but they are all either outdated (on the one hand because nobody is releasing a new one when a new version of hollywood comes out, but also because the repositories on Ubuntu are updated way too rarely. Not to mention that they are all buggy).
It would be nice to have a Dockerfile in this repository that could always create an image for the latest hollywood version and in addition to that it would be nice to always have the latest Docker image available on Docker Hub.

I can provide the appropriate Dockerfile if you're interested and guide you through the simple process of building/publishing the Docker image if necessary.

Support for Docker would be really nice to get better cross-platform support, especially for Windows.
