* Change comment format.
* Make missing VoxelManip error less obnoxious.
* Move `sort_pos` into `common.lua`, which is a required module.
* Remove local copies of `minetest`.
* Remove `worldedit = worldedit or {}` from modules.
* Replace replaceinverse with an inverse argument to `replace`.
* Added `error()`s on on invalid axes.
* Change `wip` to `TODO`.
* Rename `clearobjects` to `clear_objects`.
