* Make Codec separate from Scheme * Move EncodeOrDie off Scheme to take a Codec * Make Copy work without a Codec * Create a "latest" package that imports all versions and sets global defaults for "most recent encoding" * v1beta1 is the current "latest", v1beta2 exists * Kill DefaultCodec, replace it with "latest.Codec" * This updates the client and etcd to store the latest known version * EmbeddedObject is per schema and per package now * Move runtime.DefaultScheme to api.Scheme * Split out WatchEvent since it's not an API object today, treat it like a special object in api * Kill DefaultResourceVersioner, instead place it on "latest" (as the package that understands all packages) * Move objDiff to runtime.ObjectDiff
