Code review: Andrei (pending), Guy

Changes:
- Changed Project.getOrderedDescriptors() to return List instead of Vector, updated dbws and moxy references.
- Removed some dead Helper methods and tests.
- Added CascadeOnDelete annotation.
- Added isCascadeOnDeleteSetOnDatabaseOnSecondaryTables to ClassDescriptor.
- Added objectIsEasilyInstantiated to indirection policy.
- Improved logging to log on a flush, and log client session id when acquired.
- Added cascadeOnDelete support to DeleteObject and DeleteAll query mechanism prepare.
- Added cascadeDeleteObjects set to UnitOfWork to track cascade deletion.
- Added delete cascade support to mappings, fixed deletion to not instantiate collection if not required, not execute delete if empty.
- Changed mustDeleteReferenceObjectsOneByOne to an instance variable instead of method, compute in init.
- Changed verifyDelete to also check cascade remove mappings.
- Changed hasDependency to check cascade remove to process delete-all correctly.
- Changed cascade remove to not instantiate the relationship if delete-all can be used when private owned.
- Fixed m-m mapping to still delete if private in a unit of work (was recently broken).
- Fixed Unidirectional 1-m to not cascade delete to map keys if not private owned. 
- Added in memory only option to DeleteAll query to just update the cache.
- Changed DefaultTableGenerator to generate cascade delete in foreign keys if set, added foreign key constraints to direct collection and aggregate collection.
- Added CascadeOnDelete annotation processing to JPA metadata, refactored common relationship processing.
- Added some @Overrides, removed some dead code, change some Vector to generic Lists, some cleanup/micro.

Testing:
- Added cascade delete to JPA DDL test model.
- Added cascade delete to JPA fieldaccess employee test model.
- Added delete tests to fieldaccess entity manager test suite.

Hey James,
In bug 328937, Guy mentioned that the partitioning policies should not have
been added to the deprecated mapping basic-map and basic-collection in the 2.2 schema. The same should apply for cascade-on-delete.
