Trees and Biome generator stuff

[xoft]

There is no such noise in MCS. We have one single 3D noise for the terrain generation; there's only the wavelengths / frequencies for each direction that you can set, but those should already be good enough to match Vanilla, more or less. If you want to play around with those, set your shape generator to Noise3D, clear all the other settings, let the server regenerate your world.ini and play with the Noise3D params from there. Consider that shape generator to be single-biome, so try to optimize for one biome.
