New siege weapons

Fellere, I laughed so hard at that last post. Yes, if there are animals, you'll be able to hunt them for food - and later on perhaps build a kitchen to barbecue the meat. Once that happens, we'll also add some more vegetarian options for the long run, as managing animal agriculture in a game like KAG wouldn't be much fun - it'd be much more fun to assemble them into things like a bison team anyway.
