[WIP] Ground texture mod

[Jatta Raso]

well thanks anyway.. at least you exposed the gruesome error with the colour of trees. i'm looking at the Zeltweg airpower festival right now and the grass is as green as in COD, but the trees are way darker (and you don't get to see trunks just foliage). me thinks these things are the major reason why the map, dispite looking good, looks nothing like england hence the constant disbelief sensation
