Removed BlockMetaHandler; getMetaOnPlace replaced by more generic BlockPlaceEvent.
Fixed resources! (path format is NS/assets/PATH instead of vanilla's assets/NS/PATH - this way groups related things better)

Changed iron ore->gold block transformation to iron ore->shattered iron ore.
Removed debugging code.
Added shattered iron and gold ore. Exploding iron or gold ore adjacent to lava turns it into the corresponding shattered ore.
