Reduce the generating of townies

Hands down the worst thing about this game.

I have over 100 unplayed households. That should be more than enough for game to fill NPC roles, we don't even have that many of them. I delete every single game spawned townie with MCCC the second I see them. Poof, they're gone. Can't stand them. They all look the same, TS4 only has like 5 basic face models for random sims similarly to the pudding faces of TS3 so they're easy to spot.
