Ensure users can be deleted when foreign keys are present
This change is necessary to prevent this: mysql> delete from Users where ID = 112; ERROR 1451 (23000): Cannot delete or update a parent row: a foreign key constraint fails (`aur`.`Packages`, CONSTRAINT `Packages_ibfk_2` FOREIGN KEY (`SubmitterUID`) REFERENCES `Users` (`ID`) ON DELETE NO ACTION) As a bonus, due to foreign keys, orphaning of packages will be automatic.
