Subject: [PATCH] Default/mapgen: Tune biome points for improved disribution

Bring humidity points closer to reduce distortion of voronoi cells
Slightly reduce size of hot and frozen biomes
Improve location of glacier biomes
Remove unnecessary snow nodeboxes from tundra to improve FPS
Add missing dirt_with_snow to taiga
