Wrong Python version

Hey,

I've just tried to install this workflow, and I ran into some issues, which I managed to fix. It was all related to the Python version and the code trying to call Python from '/usr/bin/python' which might not be the correct usage for everyone. First, I had to install Python2 which is gone from the newer MacOs versions. Once that's done, get the location of Python2, and replace '/usr/bin/python' with that location in the two actions inside the workflow, and for every instance in 'reddit.py', 'workflow.py', and 'background.py'. That fixed it for me. Hope this helps!
