Previously only 'mapgen water source' and 'mapgen river water source' were checked for. Games can use multiple liquid nodes defined for biomes, many of which will not be aliased to those 2 mapgen aliases, causing floating dungeons to generate in some liquids. Now we check for liquid drawtype instead, so can remove liquid nodes from dungeonparams. Also check for 'airlike' drawtype instead of 'CONTENT_AIR' to avoid generation in 'airlike' nodes in some rare situations. This will also be needed for when we add definable biome air nodes.
