Radio2 category callbacks

Implement callbacks that are called after we've saved a category feed.

This allows us to use a category to manage a feed for a separate site, like Scripting News, as explained in this post.

Callback: config.radio2.users.dave.callbacks.afterBuildCatRss.scriptingNews, on shreveport.

This feels just right. Took all of about ten minutes to implement. I would have spent all day writing yet-another RSS generator, when I had an app, Radio2, whose only purpose is to generate RSS.

Still have a bit of cleanup to do. I want to change the title, link and description on the feed to point back to the Scripting News home page, not to the linkblog, but that's not a huge problem (the feed should work anyway).

And I really want to break with Google Reader. It's like a ten-ton weight around the neck of RSS, just sitting there, unwilling to move. I never had that many readers on Google Reader anyway, and these days most of the flow is coming from Twitter.
