Add ability to transduce values collected via clojure.core.async/into

Question

This is a trivial change that allows a transducer to be provided as the first argument to clojure.core.async/into. This feels like a common use case ... transforming values and conj'ing them into a collection, as with {{(transduce xform conj [] ch)}}.
