Title: Added fetch_revs method

I saw myself forced to add `fetch_revs` method to avoid pulling all the docs when I only needed the revisions. This saves memory (no docs occupying memory while working with revs), improves performance (I'm using Cloudant so waiting for all the docs to download is slower than waiting just for revs) and saves bandwidth (not relevant for me but could be for those running apps that have metered bandwidth)
