F.L.E free landscape editing code

Cool, please use my version that can export the mesh. I also had the idea to make a function that lets the user define 3 textures for 3 diffrent heights, one for west-side vegetation, and probably an other function that is slope-based (too steep= rock, other=grass etc.)

Later. Just a wip screen:
