Fix some issues for dateutil and argparse (#357)

Browse Source 
* Fix stubs for 2.7/dateutil. They were pretty broken.

(The 3/dateutil share some of the brokenness but that's still a TODO.)

* Fix argparse stubs.

- Container is not strong enough for choices.
- add_subparsers() returns something with an add_parser() method.
