Adds a new train station (Dispatcher) that dispatches waiting trains to a station when a dispatch virtual signal is received (target station ID is provided via the signal).
I reported it to the developers, but figured I should mention it here as well. When a train is waiting at a Dispatcher Stop with no valid destination, and you add a wagon to the end of the train, usually it just goes back to waiting at the Dispatcher in automatic mode. But sometimes it causes a hard crash of the game.
