Switch to QRunnable + QThreadPool

Get rid of SmDataCollector and do its job in small, QRunnable tasks and
let QThreadPool manage the treads.

Works well with a local Filesystem. Yet to see how it works over
networked Filesystems.

Ah, before I forget: NEVER, EVER USE QPixmap in THREADS -> Random
crashes! (Yes, I know, it's documented...)
