trap errors more gracefully?

[amy-langley]

It may or may not be worth changing, but currently submitting a malformed request gets you a 500 page with a ton of detail about the error, including stack traces and some kind of WSGI console login. This could be useful for debugging but I wonder if we should clean it up somewhat for production?

I agree. Also the current page shown is only because debug mode is turned on (https://github.com/zooniverse/aggregation-for-caesar/blob/master/routs.py#L58).

Side note, this can be done in flask by adding something like

@application.errorhandler(500)
def internal_error(error):
    return "500 error"

to the application and turning off debug mode.
