Gauntlet v1.1

Implements Graves and associated Grave Events to create a gravestone when a player dies; it will spawn at the death location and hold all items that were in the player's inventory at the time of death. It is only accessible until the gravestone is broken or the player dies again; when an active grave is broken, it will drop all items contained within it and drop a gravestone item which may be placed elsewhere at which point it will be inactive and therefore be inaccessible as storage.

Implements head drops when a player is killed by another player.

Implements serialization and deserialization for grave inventories to maintain persistence between server reloads and restarts.

Implements an auto-save task to purposefully save the game and flush cached save data; it will run approximately every 24 hours.
