thelounge Changes:
linkPreviews: Enforce TLS validity
When a URL is prefixed with a TLS scheme, we should make sure
that the remote provides a valid cert, even just for prefetches.
Else MITM of such a site is trivial.
This probably breaks some people with self signed cert, but the
age where that was acceptable is past. We have free CAs now like
Let's Encrypt.
