Papyrus: Add to the rainforest swamp biome
Previously, papyrus was limited to the savanna biome. Rainforest is a suitable habitat for papyrus. Makes papyrus a little less difficult to find. Move swamp jungletrees into a separate registration, to allow applying distribution by perlin noise to keep these away from papyrus areas. Fix error: Remove non-functional 'rainforest swamp' from the biome list for the jungle log decoration. It is not placed in swamps due to the 'y max/min' and 'place on' parameters.
