v2.6
	Fixed a serious server side crash.
v2.5
	Added the netherrack ore sheep.
	Most other mod pickaxes now shear sheep as well.
	Sheared ore sheep now have ore splotches instead of wool ones.
	Ore sheep now use resource pack ore textures for their own textures.  This means that ore sheep will take the appearance of the ores in installed resource packs.
v2.4
	Converting a sheep no longer removes its name tag. 
v2.3
	Due to popular demand, ore is again genetically inherited.
	You can now change baby ore type while in creative, just like adults, by right clicking on one with the ore you want.
	Shears are now damaged when you try to use them on an ore sheep. Ore sheep are rock solid after all!
	Wool ore sheep can be sheared with shears and drop 1-3 wool.  But how would you get a wool ore sheep anyway?
	Minor bug fixes and improvements.
v2.2
	Breeding two ore sheep now spawns a regular baby sheep.  Ore is no longer genetically inherited :)
v2.1
	Removed ore sheep "ghost" client entities.
v2.0
	Ore sheep are now bred with many different stone blocks and ores instead of wheat.
	Ore sheep now also eat netherrack, stone slabs, cobblestone and stone brick stairs, stone bricks, stone buttons, stone pressure plates, mossy cobblestone, and cobblestone walls.
v1.0:
	Added ore sheep!
