Check Version IRI for versioning OWL ontologies

[jvendetti]

When determining the version number for OWL format ontologies, the current code uses the owl:versionInfo annotation property:

owlapi_wrapper/src/main/java/org/stanford/ncbo/oapiwrapper/OntologyParser.java

Line 165 in 1d2ab90

OWLAnnotationProperty versionAnnotationProperty = factory.getOWLAnnotationProperty(OWLRDFVocabulary.OWL_VERSION_INFO.getIRI());

This was the standard location for storing version numbers in OWL 1 ontologies, but in OWL 2 the standard is Version IRI:

https://www.w3.org/TR/owl2-syntax/#Ontology_IRI_and_Version_IRI

Code should perhaps be modified to favor Version IRI, then versionInfo as a fallback.
