Added check_field_is_empty decorator to cleaning.py. This makes sure the cleaning checks are skipped when a field is empty. Note that Djanog will raise it's own ValidationError when a required field is empty before attempting to clean it. Patch by: Lennard de Rijk Reviewed by: to-be-reviewed.

        raise CommandError("This command has been renamed. Use the 'sqlcustom' command instead.")
