Refactored a bit of the TileEntity code so that ANY block may now have a tile entity. 

This is to allow modders the ability to extend blocks other then BlockContainer, and still be able to have a TileEntity.

Also added a NBTTagCompound to the base EntityClass, this allows any entity to be given arbitrary data that will persist across world saves.
This data is NOT sent over the wire in a MP situation, to have data sent over the wire automatically use the built in data watcher.
