Various bugfixes and workarounds
...
Now working in pure Lua!
Some parts of the code are very hacky (e.g. noise) and the way new and old codes have been glued together is sometimes to be rewritten.
But at least it works.

Horizontal shifting according to 3D noises:
...
makes slopes more irregular and natural-looking, allows overhanging.
This is done by generating an intermediate 2D elevation map and, for each node in 3D, add a 2D offset vector to the position, and seek this position on the heightmap.
