Title: Fix start and head in Zipper, correct comment on Zipper.move, and added test cases

I'm moving over some commits I made to the scalaz/master branch. To move these over, I branched scalaz-seven and cherry picked my commits. Let me know if there is a better way--I'm happy to do this over again.
