new map generator

researched gaussian blur a bit, and wrote up an algorithm for it, havent had the time to test it yet. also have to find a good value for sigma.

my plan is to blur it with a radius of 2 or 3 before the sprites get put on and then to blur it again with radius 1 or 2 after. i don't want the sprites to become too indestinct, but i don't want them to be too blocky either.
