v0.1.0: Finally Worth Releasing

OpenShow, at long last, can now be deployed semi-properly, using a docker image. I feel that this deserves an actual release. This system is now fully in use at my work, and has been stable and functional since its initial deployment.

This project will likely stick with major version 0 for a long while, as the architecture is not solid yet. See ROADMAP.md for some details. However, the code that exists now is fairly stable, and is in active use every week to run slides and live stream overlays.

Happy Hacking! More to come.
