Make silicons unable to unscrew the nuke

[Musketman12]

Recently sometimes I have seen nukeops and breaking into the AI core, and making the AI unscrew the nuke when it is armed. Personally I see this as kind of meta/power gamey as how would syndies know that the nuke timer goes down when unscrewed, since they are too dumb to unscrew it anyways. This also goes against the reason you can unscrew it at all which is to run away with it and kill it. It's just a dumb way to get around the screw-driver block for syndies.
