run-firefox enh: screenshots, pings, more

[gregglind]

Should run-firefox take screenshots? How often? Store them where?
Telemetry... should it print all shield-study, shield-study-addon telemetry? how to catch those?

Maybe it should screenshot every time there is a telemetry ping

THe screenshotting api i want looks more like this:

• if ENV.screenshots=true or such:

  • have spots in the addon that request "screenshotNow(filename)".

Then I can do test runs that take screenshots at all the right times.

Conclusion: trying to signal FROM THE ADDON that 'you should take a screenshot' seems... weird and not right.

I think it's better to make that an explicit part of the script run. OR if you are running manual, it is on you to take screenshots.
