Fixed a rather large issue with the mob spawner not applying on-spawn logic to mobs. Enemies would spawn without weapons, slime-type enemies would always spawn the same size, and in rare cases, mobs spawned would stand still and do nothing. I'm surprised this never got reported.

Additionally, fixed an issue where it would not spawn wither skeletons in the nether. They, along with strays, may be moved to a different card from regular skeletons in the future.

Added the ability to turn off the spawner with a redstone signal of 8 or higher. This has yet to be referenced in the manual documentation.
