Wither Cage Fix

---

Fixes vanilla bug where withers forget their targets. Can also prevent blue skulls.

Works server-side and in single player.

This mod fixes a bug in vanilla minecraft that causes Wither bosses to forget which mob they were targeting when they
unload (due to quitting, going through a portal, etc.).

Additionally, it adds a new gamerule: wither_cage_fix:allowBlueWitherSkulls (default = false).
If this is set to false, Withers will never shoot blue skulls
(whenever they would have, they'll shoot normal skulls instead).

The bug fix allows for much simpler Wither cages because there's no need to control line-of-sight when entering/leaving
the area.

The gamerule is added as an option because blue Wither skulls have basically no purpose other than to make Wither cages
more difficult to create.

Why would anyone want a caged Wither?

• They provide a fully-automatable, late-game ([subjectively] balanced) way of breaking blocks.
• The above is a nice alternative to TNT duping for those who don't want to use it (also check out
  Carpet TIS Addition
  which includes an optional patch for TNT duping).
• It's cool.

so anyone else is free to port it.
