Bug #10250: Eliminate manual test suite
Automate Tor Browser fingerprint tests
I.e. we should automate the checks against https://panopticlick.eff.org/ and possibly https://ip-check.info too. We can skip the "compare against previous Tails version" part of the manual test; what's in the test suite should always reflect that, and be updated whenever it breaks (e.g. when importing a new Tor Browser).
