I couldn't find any way to automate the ability to export the "type" of each item. There's nothing in the data that seems to differentiate one thing from another.
The best I could do was export the "blurb" part of the code... it would mean manually updating the blurb for each item, which I get sucks, but on the plus side if you accidentally wipe your database again, the manually-entered blurbs should still be in tact on the site so you can just export and run with it again.
Version 3.5 should be the version on the Gist page now. I did some testing and it seemed to work consistently. Let me know if it works okay for what you need if you use it.
