Add OWL types.
Fix lv2:minimum, lv2:maximum, and lv2:minimum (definition did not match the reality of their usage) (Spec bug found with Pellet). Move project description metadata to manifest. Remove invalid (non-DL) OWL restrictions, and use of Turtle collection syntax (there is at least one broken implementation in the wild that fails to parse this). LV2 is now almost, but not quite, a valid OWL DL Ontology.
