Added separate permission for only legacy color codes.
The current color code grants access to both hex and legacy color codes.
Also added additional hex color code format for enhanced compatibility with other plugins.
The current hex color code format still works the same as before.
And lastly, channel listening and spy/commandspy status will be automatically revoked when a player loses the respective permission.

If the player is currently focused into the channel when they lose permission, they will be set into the default channel.

As always, let me know if you have any issues, concerns, or feature requests!
