Refactored just a very few minor things.

I came across some stuff in The Rails 3 Way and wanted to knock out two birds with one stone (trying new ideas + pull request). I made a few minor changes and tested to the best of my ability. Feel free to take a look!

Also just wanted to share this syntax I learned for cleaning up routing where you're doing different things with a get or post (etc): https://gist.github.com/876262

Interesting, but I explicitly removed logic that would render in any format other than HTML simply so that there would be no confusion that the app supported anything but HTML.

I see. Removing the :xml and :json code at the very top would again remove support for such formats. I just throw it in the index of my apps to facilitate another program or person retrieving the collection via a json or xml response.
