read Lightning protection status

[Gweneph]

There doesn't seem to be a way to read if a position (or entity) is protected by lightning attractors. I'm pretty sure I could work it out, but it would be a lot more performant if the engine would do it for us.

Typo in the title.. I was very confused initially

This information is not save/loaded and calculating it on the spot results in invalid values directly after save/load, so it is not deterministic. This means this won't be implemented.
