Wayfork 0.6.0 — subscription links

Subscription links: paste the URL a VPN service hands out instead of copying its servers
one by one.

Added

• Subscription URLs, on both platforms. + Add › Add from link… also takes an
  https:// subscription link: Fetch loads it, decodes plain link lines or base64 of
  them, lists every server with a checkbox (servers already added start unchecked) and
  every line it could not use with the reason — an unsupported scheme or a bad link skips
  that line, not the import. One-shot by design: the URL is a bearer token for every
  server on it, so it is never stored, logged or refreshed. http:// is refused.
