Added PlaceholderAPI functionality and as dependency.
Added Tab.Names.Use boolean (true/false) config (please make sure to add this to your config or make a backup of your current and reload the plugin completely (restart server)).
Added LuckPerms eventlisteners (displayname does only update if it's enabled in config and something is changing at luckperms permissions on your server (such as user groups)).
Fixed related to LuckPerms eventlisteners the internal interval function and only update TabList Header and Footer if one of those is enabled or/and having content.
