Not compatible with Python 3.5

I also discovered that this doesn't support Python 3.5 in general when the JSON packet for the options is passed back to the api from the frontend. I had to run this under Python 2.7 in order to get the scheduler to run and accept new job tasks.

Traceback (most recent call last):
