* Adds "weighted random" AI law config
- Streamlines some duplicated code for law config stuff
- Makes a new "weighted random" option for AI laws, where an AI has a
random lawset, but some lawsets are more common than others.
80% normal, 20% quirky.
For those unwilling to source dive, here are the weights:
- 32% Asimov
- 12% Asimov++
- 12% Corporate
- 12% Robocop
- 12% Paladin
- 4% Maintain
- 4% Reporter
- 3% Hippocratic
- 3% Live and Let Live
- 3% Peacekeeper
- 3% Drone
* Law weights are now in the config file
