Update EnOcean diagrams
RFC 190: Updates from CPEG meeting

The minimum cardinality property is to be supported for older component
namespaces. Configuration property names starting with <refname>. are
reserved for future use by the specification. The DTOs were reviewed to
ensure there were no cycles. There were none, but there were duplicate
instances of ReferenceDTO. BoundReferenceDTO was changed to use the
reference name rather than a ReferenceDTO.
