Now using Spigot 1.12.2's new hiding API, if available (update 1.12.2 servers to latest version!); Older server versions are still supported and simply dont use this new API
This improves the accuracy of the Prevention hider severely
Also improves performance since the ForcedInvisibilityTask is no longer required with this
Removed character minimum of two characters for the main command in the config file
Fixed an error which occured when players picked up items after quitting the server (how is this even possible Spigot?)
