[Config] Security Officer Scaling

Intended for high-population servers

Open security officer positions scale with population, between 5 slots at ~40 players to 12 slots at ~96 players

Default coefficient is 8, but may be modified (or disabled) in the config.

Extra lockers will spawn if there aren't enough lockers.

Their direction changes will work even better if mob movement code finally removes all the spawn() calls. I'm not planning of adding any special code for that here.
