Update for MC 1.18

Fixes a bug where barrels would not spawn below Y0.

Auto Barrel Cleanup

• Added option removeBarrelsAfterSeconds. If enabled, the plugin will remove barrels which are older than the configured amount of seconds (even if not empty). This option will also work across server restarts. However, after server restart barrels only get removed once the chunk they're in gets loaded. Set to -1 to disable time based barrel cleanup (disabled by default).
• Prevent players from inserting items into DeathBarrels. Items can only be taken out.
• Allow barrel protection messages and barrel inventory title to be customized via the config.

Barrel Protection & 1.17 Update

• Added a new option protectFromOtherPlayers which will only allow the barrel owner to break it or access its contents.
• Players who have deathbarrel.accessprotected set can bypass the protection.
• Prevent players from creating DeathBarrels manually.
• Updated for Minecraft 1.17

Added option to remove empty barrels

When removeOnEmpty is set to true in the config, the plugin will remove death barrels which are empty when the player closes the inventory.
Updated for Spigot / Paper 1.16.2

Mechanic Improvements & Customizable Messages

• Find next coordinate on y-axis to place the DeathBarrel
  This prevents destruction of blocks at player death location (for example doors).
• Block explosion damage for DeathBarrels
  If a player dies due to explosion damage, e.g. creeper, the death barrel will no longer be destroyed
• Customizable plugin messages
• Void-death support
• Updated for Spigot / Bukkit / Paper 1.14.4

Thanks to @Ghost-chu for implementing these features and fixes! 😃

• Disabled barrel container drops to prevent people from cheating barrels by dying continuously
