the_platinum_searcher 1.7.1

the_platinum_searcher (pt) now uses Godeps to vendor its dependencies.
Yes, it is. I've referenced the ``nsq`` formula for how to use Godeps in Homebrew (see https://github.com/Homebrew/homebrew/blob/master/Library/Formula/nsq.rb#L20 ).

If there is a preferred alternative method for using Godeps in Homebrew, let me know (e.g. #29820, if it gets merged).
