Changes

Support for bulk loading of objects has been added to pm.getObjectsById. Update of a Set has been improved to not do a clear+addAll. Persist of a 1-N uni FK collection now uses one less SQL statement for RDBMS. Error reporting when detach fails has been improved. JPA JTA/nonJTA "datasource" persistence properties have been fixed. Non-referential flush process (non-RDBMS datastores) has been fixed to correctly detect newly persisted objects.
