External and internal audio players work similarly now. Fixes #950. * inherit a new ExternalAudioPlayer class from AudioPlayerInterface; * use an existing ExternalViewer class to implement ExternalAudioPlayer; * take (const char *, int) instead of std::vector<char> in ExternalViewer constructor to fit into AudioPlayerInterface; * extend ExternalViewer API to let ExternalAudioPlayer stop superseded audio player processes; * make AudioPlayerInterface::play() return an error message string to allow reporting immediate failures from derived classes; * Document AudioPlayerInterface API; * Document AudioPlayerFactory::player(); * use the common audio interface exclusively in ArticleView.
