[WIP] Ground texture mod

[philip.ed]

Very nice work, Ali!
Whilst the work that guy on the Russian forum has done looks nice, are the colours really representative of summer? It looks more like Spring to me.
It shows, though, how 3'D hederows really are needed to give the game that realistic boost.
Rather than creating new tiles, couldn't that guy have just recoloured the existing ones?

EDIT-looking at all the pictures on the Russian forum, I think the default colours are much better.
