grafx - Extensible Java Graphics Package Code

Adding empty pause and resume calls.

Adding m_internalStopped and consolidating both stop functions.

Oops, had forgotten a _stop() call. The new audio works, minus pause/resume.

Doing a little class swap-a-root, with ModernAudioClip moved to
ModernAudioClipOld, and ModernAudioClip2 moved to ModernAudioClip. In other
words pause() and resume() are now unimplemented, and the audio may not be
working at all, because we are just now about to test.

Oops, forgot to commit a _loop() call.

Removing pause() and resume() from the new audio system but besides that we're
ready for testing. Compiles at the very least.

Incremental progress on AudioDispatchQueue. Moving the meat and potatoes back
into ModernAudioClip2 class. Not working yet but compiles.

Making a tiny bit of progress in AudioDispatchQueue. Very incremental changes.

Removing unused import statements from ModernAudioClip2. Incremental change.

Making progress in AudioDispatchQueue. Far from working, but compiles.
