[Interest] Singleton application

[Nikolai Tasev]

Hi Hamish,

There was a qt-solutions class for this QSingleApplication but I think 
it disappeared in Qt5. I don't remember being able to pass anything to 
the first started process.
Doing a google search gave me this derivative 
https://github.com/itay-grudev/SingleApplication

Best Regards
