Raise events when train stop limits are changed

[notnotatschool]

I'd like it if it were possible for mods to react to train stop limits changing. I imagine this would raise an event with the associated train stop, the old limit, and the new limit. This would be useful for a mod that I am working on but have not yet released.

I second this suggestion. I've been playing around with a train scheduling mod myself, and it would be useful to be able to have an event handler trigger when a stop "requests" that a train be sent to it by increasing its trains_limit property.
