Add event for lightning striking a building

[kotrenn]

I was wanting to try out a mod where a crafting building activated based on lightning striking it. From what I can understand, this would require adding an event to the API, which Lightning Collectors or other similar structures could respond to.

You should be able to use LightningPrototype::strike_effect together with ScriptTriggerEffectItem.

It would be nice to have a dedicated event with more information than a script trigger.
