JSON additions

Worldgen

• Where applicable, Perlin noise now can have custom seed specified
  • Change above allows to explicitly specify universe seed (as celestial.config:systemTypePerlin:seed)
• Perlin noise now can be of arbitrary scale (defaults to 512, specified with 'scale' key, integer type, >=16)

Terrain

• Nested terrain selectors now get their unique seeds (displacement selector can now properly be nested inside other displacement selector)
  • Previously, all nested terrain selectors were based off the same seed
• displacement terrain selector has xClamp added, works like yClamp

Biomes

• Tree biome placeables now have variantsRange (defaults to [1, 1]) and subVariantsRange (defaults to [2, 2])
  • variantsRange is responsible for "stem-foliage" combinations
  • subVariantsRange is responsible for "stem-foliage" hue shift combinations
    • Rolled per each "stem-foliage" combination
    • Also two more properties were added: sameStemHueShift (defaults to true) and sameFoliageHueShift (defaults to false), which fixate hue shifts within same "stem-foliage" combination
  • Original engine always generates two tree types when processing placeable items, new engine however, allows to generate any number of trees.
