* When you die, all your items are stored in a gravestone at the place of death (also in water or lava,
never in the void).
* Only you can open it. To get your items back, you choose 10 % of them (rounded up, at least 1) to sacrifice –
everything else returns to the same inventory slot.
* Gravestones can't be mined or blown up.
* Works with **Grenzland**: the grave is always placed in an unlocked area so you can reach it.
* Percentage and minimum can be changed in config/grabstein.json.
