About the PR

N.A.R.C.S. turrets can now be emagged, which overrides their targeting software to shoot everyone but those with an agent card on.

Also, increases the cost of turrets in fabricators to "INS-1"=10, "CON-1"=10, "CRY-1"=10, "MET-2"=10

Why's this needed?

I was coding #5225, and I saw that emagging used to be a feature of turrets, changing the rubber slugs out for lethal buckshot ammo. While this was obviously lethal and unbalanced, I thought of a good new way to re-add it, being that it targets all non-agent card wearers.

Not everything needs to be emaggable. In this instance, I think it's better gameplay for security to be able to rely on their trusted gun-doggo to not betray them.

Material costs seem fine. This is why you should split PRs up instead of combining them.
