Title: Fetch PRs as part of git fetch

https://gist.github.com/piscisaureus/3342247

This makes it so that every time we fetch, we'll get the refs for all of the Pull Requests as well. On github/windows, fetching every PR for all time resulted in an extra 2MB of downloaded data, I'm not too worried about this from a perf standpoint.
