add __init_subclass__ to 3.6 - #813

This will require a bit of additional work in mypy because `__init_subclass__` is an implicit classmethod, like `__new__`. It might be good to provide a way to express this in the stubs.

Can you file a separate issue with the mypy project about special-casing |

Yes, I'm working on a separate pull request to mypy; agree that special-casing there is probably sufficient. I think that doesn't need to block this change though. Thanks for fixing the whitespace issue. |

Can you just link to the mypy PR then? |
`object.__init_subclass__` does not actually take arbitrary kwargs: ``` In [2]: object.__init_subclass__() In [3]: object.__init_subclass__(3) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-3-d0998253fcfc> in <module>() ----> 1 object.__init_subclass__(3) TypeError: __init_subclass__() takes no arguments (1 given) In [4]: object.__init_subclass__(x=3) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-4-81fc49abae69> in <module>() ----> 1 object.__init_subclass__(x=3) TypeError: __init_subclass__() takes no keyword arguments ```

Mypy changes are at python/mypy#2654. I think this can be merged independently of that change though. |

Thanks! This will go out in the next mypy release (0.4.7) later this week. |
