#1593 Support sound links in Dictionary pane

[Hiroshi Miura]

some dictionary (such as DSL) supports sound files.
When supporting <a href="file://bra.wav"> tag to play sound, it would be better.

It can be realized with LinkActionLIstener for dictionary pane.

The issue is related with [bugs:#1065]

    public static class LinkActionListener implements HyperlinkListener {

        @Override
        public void hyperlinkUpdate(final HyperlinkEvent hyperlinkEvent) {
            if (hyperlinkEvent.getEventType().equals(HyperlinkEvent.EventType.ACTIVATED)) {
                URL url = hyperlinkEvent.getURL();
                if (url.getProtocol().equals("file")) {
                    try {
                        String path = url.toURI().getPath();
                        if (path.endsWith(".wav")) {
                            playSound(new File(path));
                        } 
                    } catch (URISyntaxException e) {
                        e.printStackTrace();
                    }
                }
            }
        }
    }

    public static synchronized void playSound(final File file) {
        new Thread(() -> {
            try {
                Clip clip = AudioSystem.getClip();
                AudioInputStream inputStream = AudioSystem.getAudioInputStream(file);
                clip.open(inputStream);
                clip.start();
            } catch (Exception e) {
                System.err.println(e.getMessage());
            }
        }).start();
    }
