Chore: bump comment-parser to v0.3.1

- [v0.3.1 of comment-parser](syavorsky/comment-parser#24 (comment)) uses the `readable-stream` module, which allows compatibility with node 0.8 and earlier. Whether you want to support node 0.8 isn't important - for your module, this change will function identically for > 0.8, and simply won't break for *this* reason on <= 0.8 - a net win!

Closes gh-179
