World generation

 * Grove and snowy slopes
 * Decreased the chance of generating on mountain peaks.

 * In temperate and hot climates, they tend to start higher up.


 * Giant tree taiga and giant spruce taiga
 * No longer considered as cold climates.
 * Decreased the chance of mixed in with snowy biomes.
 * This caused a small reshuffle of other biomes to maintain the overall balance.


 * Springs
 * Slightly reduced the number of water springs.


 * Swamps
 * Decreased the chance of being fragmented.


 * General
 * Decreased the chance of generating cold microbiomes.
 * Slightly increased underwater magma, to increase the chance of finding air when diving in aquifers.
