Don't log IP addresses by default in flashproxy.js
flashproxy.js's debug option is too sharp for casual use. It shows what's going on but also contains IP addresses. In #9164 (closed) was originally posted a log containing lots of IPs.
Add a new query string parameter unsafe_logging to be another obstacle to climb over. Maybe don't document it.
At least these messages need to be scrubbed:
Facilitator: got client:{ host: "X.X.X.X", port: YYYY } relay:{ host: "173.255.221.44", port: 9901 }.
Facilitator: connecting to https://fp-facilitator.org/?r=1&client=X.X.X.X%3AYYYY&client=X.X.X.X%3AYYYY
