Subject: [PATCH] Revert last two commits.

Reason: https://github.com/python/mypy/issues/328

* Revert "Make fromkeys() take an Iterable instead of a sequence. (#605)"

  This reverts commit 66e8d4a14f565ea4b4502dcb5c128d5799db8ec4.

* Revert "Make dict.fromkeys() a classmethod (which it is). (#604)"

  This reverts commit 26dfcb6859950e069ef7fd6b79e9a214bf71971a.

* Add an explanation for fromkeys() being a staticmethod.
