Silk Spawners Modded Edition

silkspawners 1.8.2 pre-release 2:
fixed restore last open gl not disabling cull before begining to render next item
removed Config#setDynamicPosition as I now know that ghost entities no longer occur
made RenderUtil#getJockey() more compatible by getting lowest riding entity
fixed improper check for animationItem and animationSpawner before animating spawners
made the entities dimension id always equal to the world's since Entity#setWorld() doesn't update the dimension id for both items and blocks
