Wish List: Make active date available in item feeds

[Terran McCanna]

It would be really helpful for a create date to be included in the feed data that the Supercat code produces. Right now, patrons can page through new book feeds (in either ATOM or HTML format) indefinitely and they have no easy way to tell if they are looking at titles that were added last week or two years ago.

Example of stock 2.12 HTML list at:
