Terrain paint coated added, TerrainMat changed

Normal maps removed from terrain, as they interfered with the intention
of the art design. noise map(s) in place, are placeholder and will
almost certainly be reworked with new tiling. a new lair of paint has
been added, representing rock, and a light coating has been added to
help simulate grass foliage throughout the island. these coatings were
very quickly added (about 2 hours) and will be cleaned up over time.
dirt layer has also been approved to stay for the time being.
For now, the island should look more pleasant, and colorful, and
slightly closer to the original intention.
