Kuba's Last Merged Commits: the story of arthel159

I know a fair number of you saw Kuba (kubic71) smoke that fiddle at various tech events. And this crowd probably knew more than the public at large of his proclivity for hacking.

But today, two years without him, we merge the last of the still-open commits of his in our project.

The code actually doesn't run in today's version of Rabbithole (what we now call the bluegrass player that he was starting - at the time, we called it "chartifacts player"), but we include these commits as the history of how, where, when, and why the player started in the first place.
