Revert AI lawracks

[MomoBerry]

Personally, i'm a big fan of the law racks, but I think the tedium of changing laws with having to weld and screw on an action bar put a lot of people off. Would hate to see it reverted, as our AI gameplay is pretty barebones. Another option is keeping the old system of only being able to use one type of each law, because now freeforms are just openly the strongest and there's no other reason to use anything but them. That and there's so many types of law module types that it's gotten a bit bloated.
