Title: Added support for Data.Vector

Since it's now part of the Haskell Platform, I thought it might be a good idea to have lenses for `vector`. (I looked around `async`, but didn't see anything usable in a pure setting. I haven't checked out `split` yet.)

I added a `Data.Vector.Lens` module, as well as adding some instances for `Data.Vector.Vector` to `Control.Lens.WithIndex`.
