Modify orders and order_parts schemas: change naming of window to window_quantity due to reserved word in Postgres, add id back in orders and make it the primary key. Add hidden fields to # of doors and windows to preorder page so they can be added to orders. Modify controller so that orders and parts can be added to the database.
Remove some debug code.
Fix broken tests.
