Some more nested functor bug-fixing, including generating fresh internal names at applications; still need to debug issues with datatype constructors

28 (* To simplify Corify, it helps to apply a particular kind of renaming to functor
29 * bodies, so that nested functors refer only to fresh names. The payoff is that
30 * we can then implement applications of those nested functors by evaluating their
31 * bodies in arbitrary later contexts, even where identifiers defined in the
32 * outer functor body may have been shadowed. *)
