Subject: [PATCH] Change: Only remove orders from primary vehicles

There's no need for disaster, effect vehicles, free wagons or aircraft shadows and rotors to be checked for orders.

When a station, waypoint and a depot is removed or when an airport is replaced with another without hangars, remove orders only from primary vehicles.
