kfear’s Loot Respawn

## 1.0.0
First release. For 7 Days to Die v3.1.
- Looted containers no longer restart their respawn timer when a player comes
within 8 blocks. The deadline is fixed from the moment the container was first
opened, so scouting a POI early — or living next door to one — costs you nothing.
- Containers that are destroyed when you empty them are remembered and put back
once their timer is up, rotation intact. That covers both the ones that leave an
"opened" model behind (mailboxes, chests, safes, desks, fridges) and the ones that
vanish completely (clothes piles, luggage piles, food piles) — together about
three in five container types in the game. They then refill normally, rolling
fresh loot at the looting player's current loot stage.
- Multi-block containers — gun safes, dumpsters, mailboxes, fridges, clothes racks —
are restored across their full footprint, and are skipped if anything has come to
occupy it.
- Looking at a container you have emptied shows when its loot returns.
- Optional `AdoptExistingContainers` mode picks up containers looted before the mod
was installed, checking each POI against its original blueprint so that scenery
which was always meant to sit open is left alone.
- Quest POI resets always win: the moment one starts, everything pending inside that
POI is dropped and the reset restores it. Nothing is ever written into a POI that
is being rebuilt.
- Restores are skipped inside land claims, near bedrolls, near vehicles, near
dropped backpacks, near quest objectives, where a player is standing, and anywhere
the player has built. Air drops and dropped backpacks are never brought back.
- `RespawnDays` can override the world's Loot Respawn Days setting in either
direction.
