fix BUG-23 (subbook/series confusion), also remove warnings about sql alchemy overlaps, and had to fix bug I introduced when editing a book where the drop-downs no longer had content based on data in form, and stopped messing with books list when iterating over it, python != c :) so using another list called processed to know if the books do not need to be processed (again) - this finally fixed books on shelf
