CustomsHeadHunting

Hi this plugin aims to be similar to SaicoPvP their HeadHunting system.
So basically what the plugin does is the following:
It makes mobs that are in a headhunting level drop heads that can be sold by a player for money.
It makes players grind their way to be able to place more spawnertypes.
Spigot 1.8 - 1.18
