#19 Applet should include default sound file

I see this applet includes a possibility of using a "default sound", but no sound file is included, which seems strange to me. I suggest packaging one. I'm attaching a sample sound effect of a manual telephone ringing that might be a reasonable default. According to the webpage I originally found it on, it's in the public domain, and thus suitable for free redistribution.
