Remove trailing comma

Hi guys, 

while trying to load your latest version with python's json module, I got the following error: "JSONDecodeError: Expecting value: line 7193 column 7".

If you remove only this one trailing comma, it works like a charm. 
Hope this change would be okay for. 

Thanks in advance & greetings
