Now you can choose the fear level show style! It might be in the actionbar (like in the previous version), in the BossBar or disabled. You can also change the BossBar color and add the creepy epic fog, providing with the BossBar bukkit mechanics.
Added the /set-fear command, which allows you to change players' fear levels (check the new permissions on the Main Page of this plugin). And fixed a bug with the wrong message while using the /unfear command. Enjoy!
