grafx - Extensible Java Graphics Package Code

Using the new AudioClipStore functionality of having a 'fallback' source for
audio clips, in LaunchComputerPlayerTest. This is so that any of the bg music
clips could be loaded, w/o listing them all in code.

Adding a new key, KEY_MINIMALIST_SIDEBAR = "minimalistSidebar".

Adding 'fallback' option to AudioClipStore. This is so that background music
can be dynamically loaded from filesystem, w/o the need to explicity list every
background music audio clip in the code.

Now copying all looping WAV files, not just one.

Adding info about the new clip to README.

Adding arcadekid.wav.

Finished compile-arcadekid.sh.

Revising compile-arcadekid.sh.
