grafx - Extensible Java Graphics Package Code

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.

Adding nightmare level #8.

Adding a couple of TODO comments.

We should study this game. The computer logic seems to be off.

Implementing '--noaudio' command-line flag in launch-playback.sh script.

Adding nightmare-hi-score.blo.

Adding data/make-video-from-this.blo.

Now using the higher quality 'rocketman.wav', loaded as resource, for
background music in launch-computer-ai.sh.
