Non-stylistic changes:
* Add LuaDoc/LDoc support.
* Fix `clear_objects` area size calculation.
* Fix `clear_objects` removing player objects.
* Fix shadowing of marker entity name with player name.
* Make visualization functions use `swap_node`.
* Make hidden nodes unwalkable.
* Prevent `hide` from hiding air.
* Make deprecated functions log to deprecated stream when called.
* Fixed `replaceinverse` not using normalized node names.
* Added .gitignore.
* Bump version to 1.1.
Stylistic changes:
* Change `x = function` to `function x`.
* 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`.
* Remove `hollow_{sphere,dome,cylinder}` and replace them with a hollow parameter to each function.
* Add helpers to reduce code duplication.
* Renamed `Chat Commands.md` to `ChatCommands.md`.
