Perfected mapgen a little.

I think I'm going to make a 200 by 200 map as an overworld, and take chunks of it (probably 5x5) and derive 200x200 maps from those as actual working maps to play on. The current mapgen is pretty good for an overworld, and it's easy enough to adjust for the smaller pieces. This is mostly due to too much stuff that needs to be checked and drawn for maps larger than 200x200.

Bad pathing is definite starting to become a problem. Deer can't maneuver through the map very well now.

Still need to learn perlin well.

timber's been added, and similarly trees.

I think pathing needs to be fully resolved before I'll move on to combat, so this may take a while because I need to slog through a*.
