Subject: Custom land and water shaders

Create sandy beaches, snow topped mountains and grassy hills with a single texture, coloured
according to land height by a custom shader.
Also use the land mass mesh with a new water texture and a custom shader to create rather nice
looking water effect with depth, waves and motion.
