Line of sight for Zombies

[droqen]

Simple line of sight feature
Zombies should only move towards the nearest visible player
I tried implementing this but could not get raycasts working
(Will push PR)

Sounds good. I have some plans for the Zombie including some health, movement, animation, etc. and will work on that next week. Perhaps you can have a look when I finish and add your ideas on top then.
