Natura update

Added berries, saguaro fruit and cotton items.

I have no idea where these came from or why they weren't in the repo
already. I just found them in one of my JSTR folders.
Harvestcraft fix

Changed folder name from pamsharvestcraft to pamharvestcraft. Dumb
mistake in my initial commit.
