Subject: feat(renderer): Error pages
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Display an error page when page loading fails.

Error messages should be tweaked for messaging applications (not
browsers), because people won't neccessarily expect browser errors in
a messenger.

We still need a component to property show a certificate that failed
validation so people can decide whether to trust it temporarily.
