"me-web?" 0.12.0: every address block travels with the app

- The app now carries the whole RIPE Database list of address blocks, all five million, small single-customer blocks
  included, so the provider card and the path can name the block your connection belongs to without a connection to
  the publisher's server. The downloads are about 25 MB larger for it.
- When the publisher's server can't be reached, the provider card still names your network and its block, from the
  public address your router reports or the one the STUN test sees.
- The table is read a small piece at a time, so it takes almost no memory on a phone.
