- after aboutToFinish is working correctly the meaning for slotFinished has slightly changed (i.e. it's really only called when no playback will continue anymore: either end of playlist or stop clicked)
- when enqueing the next file signalPlay needs to be emitted to update the rest of the UI
- make stop() fade out only when in playing/buffering state
- keep muted state of the AudioOutput when crossfading
- fix typo in SIGNAL macro to fix aboutToFinish after the first crossfade
- delete the fader effect after the fade in is done
