grafx - Extensible Java Graphics Package Code

In ModernAudioClip, m_playing is no longer an array. Now it's just a boolean.

In ModernAudioClip, adding STATE_UNKNOWN and marking m_state after every call
to ensureState().

Improving ensureState() in ModernAudioClip, adding STATE_* constants.

Making nightmare level #7 a little bit harder. It was too easy.

After much testing, this is how we can implement suspend/resume on audio clips.
It's really the only way. Audio.java in base package again demonstrates this.

Adding class com.nerius.game.AudioClip, which replaces java.applet.AudioClip.
This isn't being used anywhere yet.

Fine-tuning the API Javadoc on ModernAudioClip.

Trying to get rid of some audio artifacts in ModernAudioClip but to no avail.
Java audio is very finicky, it's very difficult to work with.

Once again removing 'Audio.java' in base package.

Overhaul of ModernAudioClip. It now works with only 1.3 code. It also waits
for stop or start events, to some extent. Still needs more extensive testing.
