Reverted implementation of delete(Iterable<T> entities) to iterate over the entities as creating a query can cause the persistence provider to choke on really large entity sets. Beyond that triggering a query would require us to clear the persistence context which might not be wanted in every case. Thus an additional method deleteInBatch(Iterable<T> entities) especially available on the JpaRepository interface now triggers the query but clearly states the assumptions and side effects in the JavaDoc. Removed some obsolete finals and an obsolete method.
