That's quick work, thanks Josh! The patch looks good at first glance but I'll apply it and try it out properly in the morning

> Lots of MapReduce patterns in Crunch Lib work on PCollections, which include PTables (which extend the interface) as a special case. We should add a utility function for making it easy to convert any PCollection<Pair<K, V>> returned by a lib function back into a PTable<K, V>, and do the conversion for the user automatically when it makes sense.
