Checklists: Show name; align story entry
Fix: Stories: Clear usefulStories on init

Let's not keep stale data around.
Data: Stories: Count to designate first story

This isn't really a behavior change, but it
gives us a little more confidence that the
story we are designating as the first really
is the first story in a list.
Checklists: Sort the list of lists
Checklists: Add some margin to the list of lists

We'll want to perhaps design a better experience
for the list of lists, but for the time being
just put things in the main column.
Checklists: Do not archive stories

Checklists are not (currently) for archiving.
