CodeSnip Old Code (SVN)

* Added optional Lock parameter to TObjectDestructionMgr.HookController method and added test to test case unit to check case when Lock is True.
* Changed anonymous function in TObjectDestructionMgr.Create to raise EBug if unknown permission kind detected.

Replaced TObjectDestructionMgr.Controller property with HookController method.

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.
