[Interest] Singleton application

[John Weeks]

We derive our application from QtSingleApplication (it derives from QApplication). We acquired the code some time ago, no doubt URLs have changed since then... We are presently using Qt 5.9.5. I had compile errors when I first downloaded it, described in https://bugreports.qt.io/browse/QTSOLBUG-171. I see this in my bug report:

I cloned it from http://qt.gitorious.org/qt-solutions August 6, 2013.

Five years later it's still working for us.
