Fixed a double ban issue.
Added permissions for each option:
Permissions:
punish.use
punish.permmute
punish.permban
punish.warning
punish.severity1generalban
punish.severity1clientban
punish.severity2clientban
punish.severity3clientban
punish.severity1mute
punish.severity2mute
punish.severity3mute

There is no permission denied message, the player just cant click the item if they don't have the permission.​
