Changed permissions and fixed bug with mobs despawning
IF YOU USE PERMISSIONS FOR THIS PLUGIN YOU WILL NEED TO REDO THEM
In this update, a new permission system was introduced thanks to 811Alex on GitHub. In addition a bug was patched that caused some mobs to not despawn after players using /s.
For all these mobs that will not despawn, the players or admins will have to manually get rid of them for them to go away, as the plugin will not do this for the old mobs
