Mythos & Mortals

**Fixes**
- Minotaur now turns to face players standing behind it before attacking, instead of swinging at empty air.
  Its attacks also track you while it winds up, and the overhead slam can still be sidestepped.
- Minotaur no longer targets or keeps chasing players in Creative or Spectator mode.
- Pegasus can now be mounted with an empty hand once it's saddled and bridled.
- Pegasus can carry its rider through Nether and End portals.

- Pegasus now only accepts the Pegasus Saddle; the vanilla saddle no longer works on it.
