Title: Add playPreview method to Track object

Pretty self-explanatory, provides a new method to play previews and an example which uses it.
From the earlier conversation in [#23](https://github.com/TooTallNate/node-spotify-web/pull/23#issuecomment-20565021). The code hasn't changed since then - just submitting it as a PR so it doesn't get forgotten.
