Art's Craftable Spawn Eggs

This mod is pretty small and basic, it lets you craft spawn eggs it's simple you need to surround an egg with that mob's drop I made it this way so it would be balanced, however the Silverfish, Endermite and Magma Cube have different recipes, you get a Silverfish Egg by surrounding an egg in stone, you get an Endermite Egg by surounding a Silverfish Egg with Ender Pearls, and you get a Magma Cube Egg by surrounding a Slime Egg with Blaze Powder. You can also craft Saddles by using 5 Leather and an Iron Ingot. You can also put Rotten Flesh in any square on a crafting grid to turn it into leather. And that's about it for this mod I hope you enjoy.
