Make chickens not scared of players behind walls

[PineReseen]

Currently, chickens seem to be scared of players behind obstacles (could be the case for other animals too, but haven't tested that yet). This is quite disruptive if you want to have a chicken farm next to your house, since the chickens will constantly be making that noise and not eating from any troughs in range of the player.

This could be fixed by making the detection ball be focused around the player, and have it use some sort of ray tracing so it's more performant and also stops chickens seeing through walls.

I agree, not just chickens, but goats and rabbits and piglings.

It seems a bit unnatural that these animals freak out when you are walking around in your home behind walls and this also disturbs their eating and other things.
