Reindex fix

This refines the cleanup process and puts it in its own director.  In `Cleanup/`, we now have a script that deletes a number of test objects from each object type, and a separate one for reindexing, to be run once after the previous completes.  (Done via Jenkins configuration to ensure it happens in the right order.)

To make sure `testrecip` is not deleted, it avoids looking for items with "test" in the name for `Person` and `OrgGroup`.
