Added Head Shop (#18)

Moved ShopkeepersAPI reference to listener

Moved head shop logic to its own listener

Move checkup command join outside shopkeeper check

Refresh player head on login

+ Cleaned up imports

Use UUID instead of display name to determine if a player is in the shop

Check if Shopkeepers is present before trying to enable it

Added Head Shop

+ Integrates with ShopKeepers
+ On login, users with the `qol.head_shop` perm have their head added to the shop, if not already added
+ The shop id and the price to charge are both configurable
