RoamCode v4.0.45

Fixed

• Allow Android and Chrome to register for notifications at all. The guard that keeps a push endpoint from
  pointing at a private address tested the IPv6 fc00::/7 range against the endpoint's hostname, so every
  host whose name merely begins with "fc" or "fd" was refused — including fcm.googleapis.com, the push
  service for Chrome and every Android browser. Subscribing reported "endpoint host is not allowed" and no
  such device could ever receive a notification. The address checks now apply only to real IP literals;
  loopback, link-local, unique-local and private ranges are still refused.
