Add __class_getitem__ to the declarative Base class
Fixed issue where the :func:`_orm.as_declarative` decorator and similar
functions used to generate the declarative base class would not copy the
``__class_getitem__()`` method from a given superclass, which prevented the
use of pep-484 generics in conjunction with the ``Base`` class. Pull
request courtesy Kai Mueller.
