[PAPI Support] Add placeholders for

[spikehidden]

Is your feature request related to a problem? Please describe.
It's difficult to show the balance of just a worldguard region in a scoreboard, message, ect.

Describe the solution you'd like
I'd like to be able to have placeholders like:

• %gringotts_balance_worldguard_<regionID>% - Shows the balance of the region.
• %gringotts_balance_player_[<other player>]% - Shows the balance of the player
• %gringotts_balance_vault_[<other_player>]% - Shows the balance stored in vaults without enderchest of the player.
• %gringotts_balance_enderchest_[<other_player>]% - Shows the balance stored in the enderchest of the player.
• %gringotts_balance_endervault_[<other_player>]% - Shows the balance stored in vaults including the enderchest of the player.

Describe alternatives you've considered
Well for %gringotts_balance_player_[<other player>]% you could use the vault placeholders but for the others I couldn't find an alternative.

Additional context

EDIT:
As worldguard is not supported anymore I crossed that out but it still could be useful if you want to show how much the player has in his vaults apart of in his inventory.

Would also love to see a placeholder that allows you to output the top 10 player's balance

Even though that sounds cool, it would be really computationally expensive. Saying that, I'll have a cool at it :)
