Package our OpenPGP applet for Debian and maintain it there

This piece of software could be useful outside of Tails.

The code currently lives in config/chroot_local-includes/usr/local/bin/gpgApplet in the main Tails Git repository, which is far from ideal for a packager.

If someone wants to tackle this, intrigeri will be glad to take this script out of this repo, and to turn it into a regular independent upstream project.
