Subject: [PATCH] Modified <ListWidget> state schema to add new field
 'total_added' to keep track of the total number of times a new item has been
 added.  This new field is intended to be used to give each item a unique
 lifetime ID to be used as the React key in the items listing, as well as to
 find the item to update its future checked status.
