Ruby

Adds support for creating state machines for attributes on any Ruby class

StateMachine::Integrations::ActiveRecord#owner_class_ancestor_has_method?

ActiveModel's use of method_missing / respond_to for attribute methods
breaks both ancestor lookups and defined?(super).  Need to special-case
the existence of query attribute methods.
