Proposal: Add conspicuously missing Functor instances for tuples

Strong +1 from me. We derive Eq/Ord/Read/Show/etc. for all tuple types
of size up to 15 as it is, we might as well do the same for Functor.

(Personally, I'd even argue for adding Foldable and Traversable
instances as well, but the Foldable instance for pairs has proven to
be pretty controversial...)
