Useless horse code removed from TFC horses
Added this just because. figured it can't hurt.
Forgot we can't touch things that have to do with horse chests, since we can't use the vanilla horse chest
Horses can now be properly bred with items
Bears no longer run away when hit
Chicken Ai can now deal with not being able to reach a nest box. should also be able to see nest boxes that are slightly above it.
removed system.println
sneaky sheep run from wolves and wolves aint caring
Horses can actually be bred now- checked with wild horses, solved problem.
Added square top rendering to Quern

And you can choose to only have the round stone top, square top or both.
You can also turn off the round stone sides being rendered, used in
combination with the square top, no point in rendering something you
can't see :)
Added QuernManager to the API

Quern recipies can now be added by other mods.
Quern input slot takes only input items that are used in a registered
recipe.
If an output is different from what is being processed it will be
ejected to make room for the new item, if it's the same, it will be
added to the output if possible. If the stack reaches it's max size, it
will be ejected and what is left over will be added to the output slot.
Found a small calculation bug in the stack amount that gets leftover
Removed the possibility to add valid items without registering a recipe
Item Powder and Fertilizer were not being registered

Also removed unneeded code in ItemOre and fixed the Powder .lang keys,
and removed a duplicate quern recipe.
