Orders with direct payment

Waiter should be able to order a product (or multiple products) without the need to create a tab and then mark the order as paid immediately. In the background this will be done by creating a separate tab, ordering products and then proceeding to the pay dialog created in #3 (closed). The existence of a tab should be transparent to the user. This tab should also not be visible in the Tabs UI.

Acceptance criteria:

• A Direct order page
  • Dialog to order items similar to current ordering Modal on left side (ordering an item may refresh page (col-lg-8 col-sm-12)
  • List of currently ordered items and their states similar to current Tab display (col-lg-4 col-sm-12)
• Current order is bound to user, if he browses away and then returns the order must remain
• Payment via payment method as in #3 (closed)
