I've finally done it, and added back the abillity to remove individual bounties

Changelog:

• Players can canel individual bounties by clicking on them (if they were set by themselves)
• Operators can cancel anyones bounty (must have both lb.remove and lb.op permissions)
• The name of the person who set a bounty can now be displayed on the bounty-items (will get removed when the item is dropped)
• You can now disable the abillity to set bounties on yourself

Config changes:

• Code (YAML):

  set-by-lore : false
  shows the name of the setter of an bounty on the item
  
• Code (YAML):

  allow-self-bounty : true
  Allows players to set bounties on themselves

Lang changes:

• Code (YAML):

  #GUI - Titles
  head-lore-overflow : "&8..."
  item-lore-set-by : "&8&l Set by [PLAYERNAME]"
  unknown-setter : "UNKNOWN"
  
  #Messages - Errors
  self-bounty-error : "&cYou cannot set a bounty on yourself"
  inventory-full : "&cYour Inventory is full"
