[WIP] Ground texture mod

new patch new lighting, dusk time has a fantastic new flavour, and theres just much more light about in general, more specular effects etc.

at dusk though the green comes through really weird, really !, check it out, quick mission set time to 20:00. darkening the default textures is a must now. oo eck.
