* added to `minetest.registered_schematic` with the key of `schematic.name`
* if `schematic.name` is nil, the key is the returned ID
* if the schematic is loaded from a file, schematic.name is set to the filename
* the current mod path will be prepended to the schematic filename if it is a relative path
* `minetest.clear_registered_biomes()`
* clears all biomes currently registered
