5231	Unncessary forward declaration of std::pair	Chris Jefferson	Joel de Guzman	"fusion/adapted/std_pair.hpp contains a forward declaration of std::pair. This upsets libc++.

However, <utility> is also (I believe) always included anywhere (at least, in every test I did), so the forward declaration isn't very useful anyway. This patch just replaces it with a #include <utility>. For me, this very slightly decreases the size of the pre-processed file on both mac and linux g++.
