[3.5.2] Improved how permissions work, cleaned up wording with commands:

• Changed permissions so that if you have a permissions plugin like LuckPerms or GroupManager, the permission 'tg.user' isn't given to everyone on the server by default. Only to operators. This means:
  
• If your server has a permissions plugin, nobody besides operators will be given the 'tg.user' permission by default. You will have to assign it to a permission group. So far, the plugin recognizes PermissionsEx, LuckPerms, and GroupManager as permissions plugins.
  
• If your server doesn't have a permissions plugin, then everyone who joins your server will explicitly be given the permission 'tg.user'. I know this might be an issue for those using the permissions.yml file, but this is just a temporary fix. I am hoping to get around this by adding a config setting that lets you toggle whether everyone gets the tg.user permission by default.
  
• If you have any suggestions for how to handle this better, then please let me know!
• Also cleaned up the '/tgconfig' command results to include the new toggle settings
