[WIP] Ground texture mod

haha good stuff i like those colours. bit low res but the googley style images in there are ok colour wise. we cant have trees in the texture though !.

shaders :

diffuse = texture
alpha of diffuse = NO IDEA. maybe lighting orientated (specular brightening ?)
_N variation files are the normal channells. (RGB specific) and they produce an element of height mapping to the texture from the general lighting.
