Title: Add subPropertyOf to rdf:type for additionalType.

The semantics of `additionalType` is that it behaves like `rdf:type`. This commit creates the necessary `rdfs:subPropertyOf` statement to allow reasoners to infer this.

This also allows custom information in a microdata registry to be removed.
