We need some environment variable that can be set to disable the error-handling and allow exceptions to propagate fully so (a) we can see the traceback without going to the logs, and (b) use the browser debugger. I set that envvar up, but it doesn't work as I expected. Some investigation needs to be done there.

resolves #73

Should probably be lower-case true for consistency

@rmarow this is in a good place for you to pick it up. The general behavior works but the switch to disable it for development doesn't.

Looking to the future, I think we should not rely on this error page as a catch-all; we should catch errors that we expect and deliver them to users in a more user-friendly way, like flashing, so they don't get taken out of what they were doing. But some errors we won't expect until they happen, and this page can be our safety net.
