Stop using lists controller

I've changed the paradigm so that clicking on a list changes to the show page for that list. This follows the way that the peepcode order app selected tables. I've learned that although the ListRoute fires off at each transition, it does not have access to its parentController and cannot change the selectedList property there. As a result, I have to resort to a cheesy logical check in the click handler to see if the selectedList is undefined or if it is equal to the model id to go into edit mode.
