grafx - Extensible Java Graphics Package Code

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.

Fixing the 'bgMusic'; getting clip from 'stub' as it should be done.

Adding the capability of playing background music during game playback. The
BLO file header determines which music to play.

Adding some infrastructure for playing background audio during playback.

In BLO file header writer "embedding" background music string. Computer player
sets this. We need this for playback, somehow. How do we know if the game was
played by computer? Don't want background music for human game, only computer,
etc.

Now supporting '--noaudio' flag in launch-retry.sh.

Adding the rocketman.wav background music in launch-retry.sh.
