World generation

 * Ore distrubution
 * Increased top height limit of Badlands gold generation from Y=79 to Y=256, and increased the number of blobs.


 * Springs
 * Lava springs can now generate amid calcite, dirt, snow, powder snow and packed ice.
 * These changes allow lava springs to generate in mountains and snowy terrain.
 * Water springs don't generate higher than Y=192, and are slightly less common.

General

 * Player Spawning
 * Reworked world spawn selection algorithm.
 * Now spawns according to the same climate parameters that control biome placement and world generation: players should no longer be able to spawn in the ocean or some other inconvenient location.
