(This is a backport of the changes from #96 to the 5 branch, as requested in #104.)
Previously, <<*>> and biliftA2 were strict in their tuple arguments. Unfortunately, the Bifunctor instances (defined in base), are lazy in their tuple arguments. This inconsistency made tuples utterly useless for Biapplicative traversals. Make <<*>> and biliftA2 lazy for tuples.
