Cary Update #2

I added the change so there is a lunge range now.  The player can also stop eating by pressing a button.  The AI got improved a bit but still buggy.  There is now a eating duration instead of instantly eating a person.  The models for neckbeards change if a hunger point is reached.  The neckbears now stop a player from eating if they collide with them.  Added sound code is now sounds play when they are supposed to.
