Comment 5 for bug 1724999

In case anyone stumbles upon this, here's a stub package which brings back the Fancy plugin:

https://apt.include-once.org/backports/artful-stretch/claws-mail-plugins-dillo-fancy-insecure_3.16~HEAD-3ace185_amd64.deb

Just quickled compiled this from 3.16, but it's binary compatible with the 17.10 claws-mail. Additionally contains the Dillo plugin as more secure alternative. Please see the package description before installing it though!
