Space for Creatures

Right now you can change the Space a creature takes up, but it only works for a creature that's basically round or square-ish shaped. The size increments aren't ideal for everything. Not all animals fit neatly into this template. The most obvious exception to this would be a horse. Ideally you'd want it to take up two squares, but you can only get one square or four squares. So you've either got a pony or a really, really fat warhorse. I'd like to see this change to an X by X format, where X is a number of squares or feet. For a horse you could choose 1x2 or 5x10, depending on which measurement you're using.
