[WIP] Ground texture mod

ive been thinking about the eventuality of the SDK and what it might mean for implementing such a mod as mine. given that its simply a new set of textures that supercedes the originals. currently a package of approximatly 66 meg.

i think its going to have to be done as a full standalone 322 meg side addition to the present BoB module so people can have the choice. But presently and before its fully developed im not understanding the present layout of that module. as its split between the core and the bob modules. hmm. i would like to keep files sizes down as much as possible. but without the SDK i have literally no idea how this will pan out. for testing it it will involve the kegety dll method but for finalisation ive no idea whats going to be the outcome.

trees and close detail such as airfield grasses etc are in the core, the rest is in te BoB. it maybe the case the putting trees into the bob might still work with config file changes. but thats another world of investigation.
