Config option to add an extra 'player' item with extra details#84

Hey, back again with another suggestion, I hope that is okay.

We’d love to use things like %cmi_user_name% and others like %vault_balance_formatted% etc. So we can show the player in each page what their group is, the world they’re in, their /money balance, and their logged in IGN.

This helps them to keep an eye on their sales while they’re shopping and allows us to have a config.yml icon to enable and set an icon to, title and description, and in the description (lore) we can use some public placeholders.

Optionally it would be great if we can run a player or console command when they click on this icon, so we can ‘switch’ between player-shop and admin-shop (both your plugins).

To clarify, with this I mean in the GUI in-game to have a bottom left icon for example (like their player head) that gives additional information via placeholders when they hover over the item.
