pdftk is not in 18.04 repos and donation plugin cannot be installed

[thatchrisblack]

pdftk was pulled from the Ubuntu Bionic repos due to its dependency on the deprecated gcj package so the install of the polo-donations-plugin.deb fails.

I resolved the dependency error by temporarily adding artful repos and installing pdftk that way, but perhaps a better method would be printing a message telling the user to just install the snap?

Use the .run Installer to install the donation plugins. I'll remove the dependency from deb file.

Can confirm this also affected me on the latest version of Kubuntu (Ubuntu 18.04 base). Installing via the run file worked and pdftk was listed as not installed.
