[2.0] DDC-195 - Refactored Mapping Syntax again to be arrays in all annotations, xml and yaml drivers instead of parsing the fields in the AssociationMapping implementations.

[2.0] DDC-336 DDC-337 - Changed @OrderBy annotation to take a DQL not SQL snippet, restrict it to field names and positional orderings. Changed all test-cases and added a test-case that shows the behaviour for OneToMany JoinedSubclassPersister Managed Entities.
