Fix cv popcart

 - Added options to select (or not) only records already checked, verbose
 - Where syntax for a list of paths
 - Needed to reference o.limit rather than limit
 - populate_cart_field() referenced 'max' rather than limit, added verbose
   support
 - Rearranged (path, dbcart, hsicart) tuples to be consistent.
