v0.2.0

https://github.com/opencontainers/image-spec/milestones/v0.2.0

v0.1.0

This is a "getting started" release and makes no guarantees the v0.2.0 will be backwards compatible. Overall, we have imported the relevant docs, added information about the media types, and created the new media types for the OCI. It isn't perfect but it is enough to start having discussions with people implementing registries and build systems.
