add old nuke back to rotation

[vampirate]

Couldn't a heist round see the r-walls of the ai core become indestructable and the team has to steal the AI ALIVE and hook it into their base. Upload a virus that turns the AI "evil" and allows it to choose a method of destruction for the station.

I guess in this instance the mesh would be more advisable. Also jerkasses that rushed to check at the start of the round would get an admin slap of some sort.
