Adding info about the new clip to README.

Adding arcadekid.wav.

Finished compile-arcadekid.sh.

Revising compile-arcadekid.sh.

Advancing a bit on compile-arcadekid.sh.

Adding compile-arcadekid.sh.

Implemented looping audio in video recording of Blockout. Works!

Laying some groundwork for getting background music into the recorded videos.

In .generate-audio-track.sh copying the audio clip file/directory structure
with 'cp --parents' which isn't POSIX compliant. But we need a good way to
preserve directory structure. Thought about using 'zip' instead.

Now allowing the character '/' in audio clips, in video recorder.
