Mgvalleys: Fix missing decorations and incorrect function order
Fix missing decorations at horizontal chunk borders by adding 'updateHeightmap()' after terrain generation. Swap order of 'calculateNoise' and 'calcBiomeNoise' because 'calculateNoise' modifies the heat and humidity maps created in 'calcBiomeNoise'. Remove confusing comment, code block is not just for mods and seems essential for correct mapgen behaviour.
