World Border mod by lanxu. This is a Minetest Mod that limits the player movement within square area and shows a stop sign to the player at the border. If the world_border is changed, the player is pushed within the square area.
The border size is by default 500 which produces 500x500 square around origin. This value can be configured with a setting in init.lua
```
local world_border = 50
```
This mod may cause players to be pushed inside blocks (and by that I mean it will cause suffocation). Teleporting the moved players to a safe location is something to be implemented in the future.
