More Detailed Keep Inventory

The mod has three subcommands:
add is used to add a player to the list,
list is used to view which players are on the list,
and remove is used to delete a player from the list. Players on the list will be granted the keepInventory true rule.
Example Commands:

Add a player to the list:
/keepInventory add Steven
This adds the player “Steven” to the keepInventory list.

View the list of players:
/keepInventory list
This shows all players who currently have the keepInventory rule applied.

Remove a player from the list:
/keepInventory remove Steven
This removes “Steven” from the list, so he will no longer have the keepInventory rule.

Players on the list are granted the keepInventory true rule individually, meaning they keep their inventory on death even if the server-wide rule is set to false.
