Scott Sanderson 74277490d5 BUG: Use arrays for week/month group calculations. ...

In pandas 0.18, the behavior of ``nth()`` changed so that Grouper no
longer can be easily used to recover group labels.

Instead of using the built-in grouper behavior, we use a groupby on two
arrays we build ourselves.  This recovers the original behavior, and is
about 2x faster as a bonus.
