[WIP] Ground texture mod

yeh agreed on too much fragmented is bad. roads between is currently a good thing tbh given lack of hedge rows. i believe that for those field areas without roads between a simple slight hue change would be good. i think half the problem with the original textures is fragmented nature. radical changes from 1 field to the next adjacent. think i might try 3 similar green everywhere on the map and break it up with the rest. top left quadrant must be fragmented as much as possible. the other quadrants can be "not as fragmented. 1 quadrant should have higher frequency lighter fields.
