General fixes / tweaks to animals. Pumpkins and mushrooms can now be eaten, not just used in meals. Pumpkins no longer have the weird face texture when spawned in the world. Tweak to HotWater blocks as suggested by Emris. Ai tweak to EntityAIAvoidEntity, should now be possible (albeit difficult) to sneak up on deer. Tweak to EntityAIPanic, now animals run in a direction generally away from the entity that attacks them, and some animals such as deer and horses scare other deer or horses around them when panicking.
