rebased #2368
Previously, the value of 'mapgen_limit' was not used to limit the spawn position. If a friendly-biome spawn point is not found within a small world, spawn point falls back to the engine spawn point, which has a larger chance of success.
To avoid respawn position being possibly very distant from new player spawn position.
Disabled in mgv6 and singlenode mapgens, by setting, or if 'static_spawnpoint' is set. Cleanup format of minetest.conf.example.
