Added:
- option to make specific clients (by UID or group IDs) to be immune against this script
- option to make specific group IDs blacklisted (blocked), so that no one can assign them
- option to disable self group management (using command on yourself)
- new and fully translatable messages (you can also disable them completely!)
- code cleaned up
I tried to test everything and it seemed to work, but there still may be bugs, so please report if any occurs.
