showing a "no lists" message when no lists exist
added sequence and status_id to this class, which already existed in the database
populating a list of statuses, and I added a default_status to config.yml
I'm still not completely happy with my many-to-many solution, because I do care about two columns in that table.  So I need to fix these relationships so I don't have to do hacks like this.  Having said that, here's a hack.   A method to set the default status of all the items for a given list.  This shouldn't be necessary, but until I want to tackle the relationships problem, it is.
