CodeSnip Old Code (SVN)

Replaced private object destruction controller of TDBDataPool<T> with an instance of TObjectDestructionManager to permit or deny freeing of data items in the pool.

There was a duplicate name problem with the new "Database" namespace so this was altered to "DB". All units in the namespace were renamed accordingly. All related test units were again renamed in line with their related "DB" units. Unit references etc were also adjusted.
