Allow backup in one place

If there’s no all in one backup, then perhaps the commands for backing up/restoring can be found in one place!

Move (or copy) the controller settings backup commands to the Controller Backup page and remove the warning: This does not back up your controller settings, only your bank data. To back up your Controller Settings, go to the Controller Settings tab.

The Controller backup function is in the controller settings tab because loading the controller backup file currently just loads it into the editor, and not directly into the device. Then you can view/edit the settings before saving it into your controller.

It’s not part of a full backup yet where the settings gets written directly into the controller - more work still needs to be done.
