Add RDFS and other namespaces new to UCO 1.0.0

RDFS and OWL are receiving aliases for in-common spelling in adopters'
code.  OWL also specifically got further support in some UCO issues.

This patch also adds a `Namespace` for the import of the Collections
Ontology, and the new UCO namespace `configuration`.
