Updated menus to work better with list item linking

Lots of changes made (almost a refactor <--- four letter word to me...
- Menu Items collection is now the "permanent" storage location for menu item for any day.  So, if i set Green Chile Chicken Enchiladas, Beans, and Rice as an item for a day, it will be stored as a Menu Item for later use.
- Linking menu items to items that can be added to a shopping list - This has been updated to be more reusable. So as you re-choose a menu item that's already got list items linked, it just shows up for you to use to build a shopping list as needed.
- Deleting menu items from a menu - changed to delete them only from the menu, and not from the database.
- Dashboard updated to pull today's menu item from the menu, and not the menu item list.
