[WIP] Ground texture mod

[philip.ed]

At the moment, the game really needs a blue atmospheric haze to make the LoD a lot smoother and realistic.

With that in mind, Ali, have you seen this before?

(also, check out their nimble cloud-generator. It certainly looks good to my eyes. It's hard to tell if the effect is over the top or not, but I'd imagine it's adjustable)

EDIT-apart from the blue fields, the old tiles look much more realistic; clear areas of foliage and trees, and apparent borders to the fields as well.
