To avoid spawn search failing in new specialised mapgens Increase spawn search range to 4000 nodes Add getSpawnLevelAtPoint() functions to EmergeManager, class Mapgen and all mapgens Remove getGroundLevelAtPoint() functions from all mapgens except mgv6 (possibly to be re-added later in the correct form to return actual ground level) Make mgvalleys flag names consistent with other mapgens Remove now unused 'vertical spawn range' setting
