Deprecate Documenter.get_object_members()

At present, the implementation of Documenter.get_object_members() is
only for class objects.  In fact, no subclasses use it (all of them are
overriding the method).

This deprecates Documenter.get_object_members() and copies it to
ClassDocumenter.get_object_members().
