Changes to the playerhead command: It now generates a head with the texture stored inside. This should be much more performance friendly since the texture won't need to be downloaded every time the chunk with the head inside is loading.
Permission errors fixed: I got told about some permission-nodes not working. This should now be fixed. Make sure you check the section "permissions and how to change them" at the overview page since some nodes might have changed. If you discover errors please leave me a message.
