Title: Made some changes to world gen

I have added a 2 deep base layer of stone, reduced the height at which the flat areas of sand appear and tweaked some of the simplex constants in order to get a slightly less "rounded" look to the terrain.

I have also added the use of simplex noise to the generation of trees, in order to give them a more natural look.
