mandos-ctl: Refactor

* mandos-ctl: Reorder everything into logical order; put main() first,
              and put every subsequent definition as soon as possible
              after its first use, except superclasses which need to
              be placed before the classes inheriting from them.
              Reorder all tests to match.
