Adding a Penumbra Monster /!\ 1 New Problems

[Jordo76]

I tested it and the dog won't follow pathnode as Hardam said, so now the thread will treat 2 new problems,
1)How to make the dog compatible with Path Nodes
2)How to do in sort that the infected chase you when he sees you (Hardam said if he see you 0.5 seconds we won't chase you but if it's 1 second he will)
