commit progress to getting list artifacts working
add listPublishedArtifacts and listUnpublishedArtifacts to
PoddArtifactManager
add published and unpublished constants to PoddWebConstants
Add partial implementation of Get(rdf) to ListArtifactsResourceImpl
Add tests for listPublishedArtifacts and listUnpublishedArtifacts
bump to sesame-2.7.0-beta3-SNAPSHOT to get access to new
QueryResultHandler features
Add PoddSesameManager.getOntologies
rename method that had a confusing name
more implementation of listing artifacts
add more tests for getOntologies
start reworking the definition and use of PODD_BASE_INFERRED_VERSION
move methods from PoddRepositoryManager to PoddSesameManager

most queries, with the exception of those that are temporarily in
SparqlQueryHelper, are run in PoddSesameManager

this leaves the PoddRepositoryManager as solely an interface to get
connections and manage the context uris for management graphs
switch to using InferredOWLOntologyID to avoid splitting up the ontology
into two parts
more work on updating versions
remove fixme note
reorder statements for ease of browsing
move RdfUtils to api/src/main/java and change name to DebugUtils
add more conditions to the
PoddSesameManager.updateManagedPoddArtifactVersion method
update implementation to match new semantics, particularly
poddBase#inferredVersion
update tests to match new semantics for the updateCurrentVersion
parameter, where the current inferred version is not modified anymore if
it is false and there were previous versions
