broken temporarily, trying to convert to use ontology browser service
manage restlet-utils versions
add CrossOriginResourceSharingFilter
change back to application/rdf+json for request format
add DataHandler.downloadOntologySubset
bump surefire and failsafe plugin versions to versions that use the new
junit-4.11 features
switch from RepositoryResult.asList() to
Iterations.asList(RepositoryResult)
Merge branch 'broken-jquery-ajax' into develop

Breakage was due to the lack of a CORS filter, which has been added to Restlet-Utils and used in OasWebServiceApplicationImpl now
