If you played e.g. an audio-only file and something bad happened that interrupted playback, the exit message could say "No files played". This was awkward, so show a different message in this case. Also overhaul how the exit status is reported in order to make this easier. This includes things such as not reporting a playback error when loading playlists (playlists contain no video or audio, which was considered an error). Not sure if I'm happy with this, but for now it seems like a slight improvement.
