protocol change: supply list name in the list of lists

protocol change: supply list name in the list of lists

the idea is that an app would want to have the name early in order to be
able to display the list of available shopping lists, and later, after
the user selects a shopping list, it would retrieve the items

also, it makes more sense this way since the lists_version thing is a
property of the list of shopping lists and is changed upon a list rename
