[RULE CHANGE] Make overrides and precedence no longer apply to AI laws.

[LeahTheTech]

Having the AI going psycho hinge on the difference in definition between override and precedence definitely contributed to a lot of the frustration around AI law jank (have been threatened with kill switch for arguing about it), so with the law rack having been around a while I think we could definitely see it gone.
The zeroeth law slot would probably have to exist, otherwise any attempt to rogue the AI is going to go: get into upload -> remove law 1 to insert funny law -> AI gets informed it can now murder humans -> get instantly annihilated by the turrets while the AI laughs maniacally.
