Update Wrapped instances for lens-4.0

[bergey]

Do not merge until the rest of diagrams is similarly updated. Opening the PR to make sure anyone else inclined to build against lens-4.0 finds it.

lens-4.0 changes the interface for Wrapped, including reversing the order of type parameters. All instances and uses need to be changed.

The commit below is sufficient to build -core.

Incidentally, our Travis builds with GHC HEAD are hanging up on MonadCatchIO-transformers-0.3.0.0, which is deprecated package and a dependency of lens-3.10 replaced in 4.0. (I believe lens 4 is out this week because we're expecting a GHC 7.8 RC.)

Oh, excellent. I may put a bit of time this afternoon into seeing if I can get our travis builds working smoothly again.

I was just looking at that, and had one thought, which I just pushed. Have to run now, though, and I probably won't have more time until tomorrow.

You'll also need Rewrapped as well as Wrapped now.

By splitting them we were able to greatly improve type inference.

The direction change came from making them compliant with the prism argument order, as evidenced by the current _Wrapped naming convention mirroring the prisms for constructors.
