Allow fast transferring out of automatic trains that are not in a station

[Quezler]

When trains are in automatic mode you cannot control+click items out of them, this would be useful when clearing clogged stations due to oversending by just being able to take it out of the train without having to open the gui, strangely you can control+click insert items into them already, but it would be quite nice if automatic trains didn't have to be in a station in order for the player to intentionally interact with them.
