scratch-qt project

[knitzsche]

Over the holidays, I scratched an itch to write a Qt/QML/C++ threaded 
app snapped with ubuntu-app-platform.

Goals:
* C++ backend using controller/worker thread approach so QML GUI is 
non-blocking when user taps buttons and backend methods run
* Concurrent execution of backends
* Easy to use custom QML item/C++ plugin supporting the above.

So it's my approximation of a responsive and extensible dashboard style 
QML/C++ demo app based on ubuntu-app-platform libs.
