ME: Ability to set AI use of external lights (most importantly AC, but also ships, land units)

[twistking]

We would need an AI option to set use of ext lights: Possible options: "Auto", "force off", "full", "tactical"...

This will get way more important once ED finally gets the visibility distance of ext lighting fixed, but i feel that this may be very soon with the PG map already having improved ext. lights for the autogen ships.
