BIOMES!

Biomes work now! I've put in a pretty big effort to make sure they match up with exactly how they are in the game, rather than just the raw randomly generated values.

The only part that doesn't work quite right is what some other map software has called shallows, and I've done the same here. I think I'm still working on getting this to match up exactly with the water level in game, but it's got a ways to go, so you might see things like a bit too much swamp covered in water, or a bit to little meadows, but it should be good enough to give you a rough idea of where to expect water!

Now that biomes work I'll be getting to work on some more user friendly sorting/filtering features!
