Single list

I changed a few things on routes and the views, since we setup the other day as I finished off the test/code.  Currently, this branch tests and passes a successful and an unsuccessful creation of a new list.  The code matches as such in the User's "My Lists" tab.

Before I move on to adding items to a list, I also need to limit the My Lists view to only show the current_user's list and not everyone's lists (as it does now).
