Sub orders finish

This is it for the night, I apologize if the code got wonky. It probably needs some serious refactoring. At the end of the night
-suborders/orders are done except for address/billing/payment info, but it shouldn't be too hard to wire together
-supplier back to order and create new item buttons is be at the top for clarity
-homepage is be consistent between calling items supplies or calling items items
-cart badge shows number of uniq items, not total quantity of items
-Can able to access a Supplier using some sort of URL slug.(this made our site slower..)

goodnight.
