Title: optional apiVersion parameter for allowing PivotalTracker v5 API

I found that the 'filter' parameter wasn't working in the v3 API, however it works fine in the v5 beta API. So I did an experiment to make node-pivotal work with the v5 (beta) API and it worked great. So I'm contributing it back for anyone else interested in using the v5 API with node-pivotal.
