Removed the freeze-effect function that slowed down and prevented the player from jumping while listening because, in case of an unexpected server shutdown, it could leave players without movement speed or without the possibility to jump.
I intend to add this feature again, but not until I find a more efficient and bug-free method.
Important: ProtocolLib has been replaced by PacketEvents (since it receives more updates and is much easier to use), so you must add it to your server.
Fixed an issue where changing the radius of a level had no effect.
Added a command (/listenmode toggle) to change the state of the ability on/off.
Added a command (/listenmode) to open a upgradeable ability GUI, where you can buy updates to maximize the range of entities (required Vault and economy provider).
