Planned additions

 * A way for mod/plugin makers to implement new commands and register them in a simple way.
 * Animation / Entity Models
 * Could possibly include model changes via NBT.
 * Would be implemented via resource packs.
 * This will make better use of changes in the code, so map makers/mod makers can create better/new mobs.
 * Basically what had happened with the block data change in 1.8.
 * May take some time before it is fully finished.
