Update to workshopper v1

[linclark]

I noticed that this was using a pre-v1 version of workshopper because the ACTUAL/EXPECTED output was harder to read.

Let me know if you're interested in switching over, I'd be happy to help.

I did start a v1 port a while back… not sure where it went but it's definitely something I'll be doing at some point.

If you're interested in PRs to help with it, post here when you have the branch started and I'd be happy to work on it.
