Please back-port cloud generation fix from 1.12 to earlier branches.

Version Information

Minecraft: 1.10.2
Forge:
Mantle:
Natura: 4.0.82

Natura/src/main/java/com/progwml6/natura/world/worldgen/CloudGenerator.java
The Following line was changed in the 1.12 branch but the cloud generation behavior is still the same in 1.10 (z=x: [lines 116 and 245] zSpawn = xPos + random.nextInt(16);)

Clouds spawn in one long line from -x -z to +x +z

Steps to Reproduce

Start a new world in 1.10.2 with clouds enabled.
