[Splints]

I have no strong feelings about the details of the implementation, but I do really like the more physical and clearly visible aspects of how laws work now that they are tied to physical items. There may be room for improvement with how laws are fixed, the time required to pull them out or put them back in, or any other details, but I think those can be fixed without just tossing out the whole new system. If we wanted to make it fast, that could be as simple as removing any timers or steps beyond taking things out and putting them back in.

Again no strong feelings myself about which way to balance things, but I do like the general idea of the new system.
