Quark

- Client: Added shiny animals to the random animal skins feature. (1 in 1024 chickens, cows, or pigs will be shiny and have a variant skin)
- World: Fixed foxhounds not being classified as hostile mobs for some cases.
- World: Foxhounds now only spawn if the light level is low.
- World: Lowered the default foxhound spawn rate by a lot. If you already loaded the game with the old config you'll have to go into the foxhounds section in the quark config and reset it to default.
