Add the ability to manage different zones

[xkokushox]

If the user selects a new delivery address from the summary screen, we need to check the available menus that retrieve the server from that location:

• if the menu exist in the new ones (Compare the current MenuId we are using with the new ones):
  • Check the new appState:
    • if "build" save the new address and return the user to the summary screen.
  • else use the current logic (Show bummer | error screen)
• else (menu doesn't exist)
  • Check the new appState
    • if "build" prompt the "Change Zone" YES/NO dialog:
      • if YES selected clear order, save current address and send the user to the build screen again with the new menus
      • else dismiss the dialog
    • else use the current logic (Show bummer | error screen)
