fixed wf template for datacite OAI sets
Incremental transformation for Datacite OAI sets
To support incremental update of projects in the database, useful functionality of IncrementalTransformationJobNode has been extracted to a superclass. Wf template for entity registries has been updated accordingly. Wf templates for other types of ds that were already in incremental mode have been updated for the new param name inherited from the superclass.
