Accomodate to new shader changes

[BlackYps]

I had to rework how the new shaders work in the game. This has implications for the functionality of the toolsuite and the current sunset biome that uses them. This requires to temporarily disable the sunset biome. If we didn't do this then we would have to release the new map generator and the game patch at exactly the same time, or maps using the sunset biome would be temporarily broken. After the game patch we can enable the biome again.
