Bug#881379: Retitle #881379 to ITP

[Carsten Schoenert <c.schoenert@t-online.de>]

I played around with CardBook and picked up the packaging thing Minkush
hast done and merged all together into git tree + git-buildpackage based
Debian workflow.

If someone want's to pick up feel free to take the git tree from

  https://salsa.debian.org/tijuca/cardbook

and adjust to your needs. I've installed the package that is built from
the source but didn't have done any deeper testing.

The packaging is using mozilla-devscripts with the web_ext debhelper
snippet so the package name is fulfill the current name schema related
to the introduction of WebExtension in FF and TB.

Also feel free to ask for a sponsorship if required.

Regards
Carsten
