Add biome color computation

Browse source 
Rather than using fixed values for all biomes, generate grass and foliage
colors based on (height-dependent) temperature and rainfall parameters.

This changes a lot of colors; in general, the new colors should be closer
to the actual Minecraft rendering. It also fixes a few colors that were
completely off (like in the badlands biomes) and adds the MC 1.13 biomes
(which were rendered in black).

Some of the newer biomes (warm/cold/... oceans) don't have proper
parameters yet, and we do not derive the water color from the biome yet.

Fixes #1.
