Added some new natural-id related features:
Ability to perform a multi-load based on natural-id - see Session#byMultipleNaturalIds
Easier application of compound natural-id values - see org.hibernate.NaturalIdLoadAccess#using(java.lang.Object...) and org.hibernate.NaturalIdMultiLoadAccess#compoundValue
First implementation of proposed concept of event-less listeners - here, pre- and post- listeners for load-by-natural-id “events” but with no event object.
