A Refactoring Story

While thinking about this week's screencast, I happened to do a pretty big refactoring on one of Destroy All Software's controllers. I translated a confusing mess of exception rescuing into a more sensible action, pushing validation and special cases down into lower-level classes. We'll look at the before picture, the changes I made, and then the after picture. There are naming changes, structural changes, and some important Rails behavior that was a little surprising. This is a departure from the normal Destroy All Software style, so please let us know what you think!
