New Cow Beef

This mod adds two new mobs:
Blue Cow: drops Blue Beef.
Gold Cow: drops Gold Beef.

Blue Cows can be found at any Ocean biome.
Gold Cows can be found at the Nether Wastes biome.

At the moment, they look the same but with their respective drops which have the following effects:

Blue Beef: Gives you the Conduit effect, providing water breathing for a while.
Gold Beef: Gives you Fire Resistance, allowing the player to swim on lava for a couple minutes.
