Sortable list with dojo 0.9

This is a quick proof of concept of a sortable, data-store backed list (using dojo 0.9). The store (a dojo.data.ItemFileReadStore instance) does the sorting. Each list-item has an id, that is mapped to the store item identifier. So when the re-sorted list comes back I just look up the list-item node and appendChild it to move it in the list. The store has 52 items (its a list of states) and seems snappy enough - faster certainly than re-creating the list-item elements and re-rendering the whole thing each time.
