Permissions Update

Permissions have finally been added!

• You can now categorize commands (2ae1ad9)
  • This changes the command's permission to commands.<group>.<originalName>
• Commands require permissions (77ec59e)
  • If a command has a category, the required permission is commands.<group>.<originalName>
  • Commands without categories require the commands.<originalName> permission
• Commands can now be permissionless (c3ec80b)
  • This was the behavior prior to 4.0.0
• Argument is no longer exported (7c350ce)
  • Use argTypes.generic instead
• The version was bumped (e267009)
