Request: List of recently modified posts/pages/documents

[sbseltzer]

I'm hoping to add functionality to my blog that not only shows recent posts, but also files that have recently been included in a commit. A sort of "recently modified" list would be possible. That way readers could see when a page or post or collection document has been recently modified.

I added changed_files to commit data in #13. Hopefully that should work for your use case. Release v0.1.2
