Completely change biome code again

Browse Source 
Turns out my previous grasp of how Minecraft does this was wrong.

This seems to be the correct way. One side effect is that biome data
now has less resolution. One only really notices this when looking at
water, for which Minecraft does not even use the water colours for
in-game, otherwise I can't really tell a big difference.

Fixes #1698.
