provide user access to log output

Bridgy does a brilliant thing providing users access to (a sanitized version of) the log. It's invaluable as a developer trying to integrate with Bridgy, and would be a TON of work to surface the same diagnostic information via a proper UI.

I would probably handle it in a slightly different way, creating per-user logs and letting a user access only their own log files using an access token.
