me-web? 0.6.0: provider notes from shared checks, and the internet seen from eight places

- Notes on providers in any country: findings people choose to share are counted on the publisher's server, one
  vote per network. A total appears on the provider card only after a person has reviewed it, and only when at
  least five different networks of that provider agree four times in five; the card says how many agree.
  Notes researched by hand still come first, and on mobile data the totals for the mobile network replace the
  notes about home lines.
- "Connected to the internet through" now comes from eight RouteViews collectors (Oregon, Ashburn, London,
  Sao Paulo, Johannesburg, Dubai, Singapore, Sydney) instead of one in Oregon, each counting the same, so
  networks far from the United States are described from nearby. A network that only exchanges traffic with a
  collector's neighbour is no longer listed as one of its upstreams.
- Ready for measuring servers outside Europe: once the publisher adds one, the app times each server and runs
  the speed test and the test from outside against the closest. None exists yet, so nothing changes today.
- When me-web? has no notes on a provider, it says that findings shared at the end of a check help write them.
- The privacy page states the rule for publishing totals.
