CodeSnip Old Code (SVN)

* Added new UTestHelpers unit to unit tests project to provide commonly used code for use by test cases. Only content is TAlwaysFreeController class. (Neglected to add UTestHelpers to SVN repo - see r980 for rectification).
* Modified various test case units that provided their own implementations of TAlwaysFreeController to use version in UTestHelpers unit.

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.
