Add "Manage Neighbourhood" - Control Townie Creation, Assign Your Sim as NPC!

Yes! I loved how Twallan's mod for TS3 could assign anybody to NPC roles, and I really, really, want to be able to do it in TS4. Why assign a random badly-dressed sim that I don't care at all about to a role when I could be using Sims that I actually already have a story for?

If this were the case, I'd be making a whole lot more Sims!
