Running flask in debug mode (for autoreload)

[fredcallaway]

I'm embarking on a major backend extension and it would be great to not have to restart the web server any time I change the code. This is possible with vanilla flask apps using debug mode. But I can't figure out how to get psiturk to use debug mode.

I tried adding app.config.from_pyfile directly to experiment.py (following the idea mentioned in #250) but that didn't work.

Is it possible to run psiturk without gunicorn, i.e. calling flask directly?
