Auto Group Remove - Luckperms Addon

Another quick plugin, this time for LuckPerms:

Have you had enough of your staff members vanishing for weeks without a word?

With this plugin you can add automatically renewing temporary groups to your players/staff

How it works, example:

• You add "Asder" to group "admin" with "14d" renewal time
  • /agr user Asder parent addtemp admin 14d
• Now "Asder" has to log in at least once every "14" days if he wants to keep his "admin" group
• If he logs in, the timer resets again for "14d"
• If he doesn't log in, the temp group expires and he gets deleted from the plugin's config on his next login

Permission:

• agr.edit - allows adding & removing renewing temp groups to/from a player
  !! currently ONLY give this to someone you REALLY trust, with this node one can add ANY user to ANY group!!

Commands:

• /<agr|autogroupremove> user <name> parent addtemp <group> <duration>
  adds <user> to renewing group <group>
• /<agr|autogroupremove> user <name> parent removetemp <group>
  removes <user> from renewing group <group>
