BANG Adding AI: give them basic memory.

When fighting a difficult mob (like the Ender man), part of why you can cheese the mob is that the pathfinding acts like it has already forgotten where it has flown from when you hit it. If it could remember something like the last block position it was in so it could try to avoid teleporting there again, or pathfinding there. Ender man is just one example but I think it would improve mob ai immensely. Thank you for reading! I appreciate it very much.
