Generates a flat world with nodes appropriate to the game.
Unlike the built-in "flat" generator, this doesn't add any biomes so there are no trees to clear before you start building!
Based upon DragonWrangler's mg_superflat but instead of introducing new grass and dirt node types it uses mapgen aliases to adopt default:dirt for the Minetest Game or mcl_core:dirt for Voxelibre. Other games supporting these aliases should also work (but haven't been tested).
To use the map generator:
- create a new world in the game of your choice
- set the map generator to "singlenode"
- enable the "flatland" mod
- start the game (play/ host)
