Feature 1154 & 73: NPCs react to crime
Feature 1154 & 73: Crime and NPC reactions
Ai pursue now controls guards pursuit of crimes

Should extend AiActivate in the future
Moved mWitnesses into Player. resetCrime for paying fine.
Replaces broken code with todo
Use duration rather than frame counts.  Stops false detection of being "stuck" with high frame rates (e.g. indoors).
Crime is now checked every frame call
Cleaned up code
Per-cell pathgrid data and calculation moved off PathFinder.  Now the edge cost calculations and strongly connected component searches are done only once per cell.  Per-actor data and methods still remain with PathFinder.

This version still has debugging statements and needs cleaning up.
