## 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
 * `mix` terrain selector got `mixSeedBias`, `aSeedBias` and `bSeedBias` fields, whose deviate respective selectors seeds (default to `0`)
 * `displacement` terrain selector has `seedBias` added, which deviate seed of `source` selector (default to `0`)
 * `displacement` terrain selector has `xClamp` added, works like `yClamp`
 * `rotate` terrain selector has `rotationWidth` (defaults to `0.5`) and `rotationHeight` (defaults to `0.0`) added, which are multiplied by world's size and world's height respectively to determine rotation point center
 * `min` terrain selector added, opposite of existing `max` (json format is the same as `max`)
 * `cache` terrain selector removed due it not being documented, and having little practical value
 * `perlin` terrain selector now accepts `type`, `frequency` and `amplitude` values (naming inconsistency fix)
 * `ridgeblocks` terrain selector now accepts `amplitude` and `frequency` values (naming inconsistency fix);
 * `ridgeblocks` has `octaves` added (defaults to `2`), `perlinOctaves` (defaults to `1`)

#### 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.

### player.config
 * Inventory bags are no longer limited to 255 slots
   * However, when joining original servers with mod which increase bag size past 255 slots will result in undefined behavior (joining servers with inventory size bag mods will already result in nearly instant desync though, so you may not ever live to see the side effects; and if original server installs said mod, original clients and original server will experience severe desyncs/undefined behavior too)
