Update the status of each module as it completes

If I run multiple modules at once I would like to see the status of each one as it completes. See this video which shows the problem.

Yes, I've been aware of this since the beginning. I think it is because everything is running in a tight loop and the UI never gets a look-in to refresh itself. It looks like the processing should be put on another thread or use BackgroundWorker:

May need coordination with #47.
