Creating routes

[Dokhu]

When creating a new route the system should allow us to choose any aircraft that is in the full list of aircraft in te game and not necessarily of our own and then when the route is created the system must require that the same type of aircraft Chosed from the beginning be selected and then clicking on the Fly route button. So we can create any route to be selected at any moment in any aircraft of our own but the same type choosen when creating the route.
