Merge duplicate recipes. You might find you have two differently named recipes that are in fact the same item. This can happen when import from someone else'e database or when more than one person works
on a single recipe database and two identical recipes are created but with different names.
This option lets you select any numner of identical recipes and the program will replace all instances of each recipe in recipes, menus, etc with a single selected recipe. The program will also optionally
delete the unused recipes after the merge is complete.
