Chat Formatting, Grab Rank From Vault

Simple suggestion that I hope can be implemented.

Since Vault is already a requirement for purchasing kits ect, the chat listener there please be an option to pick up the players current rank from vault to be formatted into the chat.
This will help for distinguishing staff from players ect.

Example;
prefixWhenAlive: '%Prefix% %Name%&8:&f %Message%'

Thanks Lib.
