Registries API

[SpaceWalkerRS]

Minecraft did'nt have registries until 1.4, and the implementation changed a few times. This API provides an alternative with a more modern feature set that's available for all Minecraft versions.

Events

The BOOTSTRAP_REGISTRIES event is fired on game start-up, during bootstrapping. All registries should be loaded before this or in a listener to this event. Bootstrapping registries may happen before this, but will be forced right after this event anyway.
