Revert the AI law racks

[amylizzle]

The negatives:
- No more possessing Freeform module for wraiths to rogue AI's.
- Harder to get the AI to go rogue without stealing an ID.
- Clear visibility of how much laws are installed
- No way to make another upload point without the mechanic scanning the AI rack.
- Once the rack gets destroyed, AI's tend to go to standard laws and the fun is over.
- 1 free form law, that's it... if you want multiplue laws you gotta cram it into 1 module.

Few points on this:
- Possessing the freeform as a wraith was enabled to begin with, but was later explicitly disabled by another commit in the name of balance, although I can't actually find said commit. Probably someone should raise a thread about it, it seems contentious.
- Someone is making a rack shutter that obscures the number of laws in the rack, plus with the AI expansion modules Azrun recently proposed, there are legit reasons to have more than asimov in there. I lean more towards Azrun's solution, but there's room for both.
- There is a blueprint for the law rack in the CE's locker, as an alternative to breaking into upload and mech-scanning it.
- Freeform module (and indeed all modules) are mech-scannable. You can print a whole set of freeforms if you like!


In general though, I'd say the response to law racks has been generally good. There were some teething problems, but I think those have largely been fixed, or are in the process of being fixed (ie shutters). Obviously I'm a little biased here.
