add superclasses to Applicative and Traversable

Functor is now a superclass of Applicative, and Functor and Foldable
are now superclasses of Traversable.  The new hierarchy makes clear the
inclusions between the classes, but means more work in defining instances.
Default definitions are provided to help.
