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.

Making a carbon copy of ModernAudioClip as ModernAudioClip2, in order to
implement the new framework without disrupting existing code for now.

Making more progress in AudioDispatchQueue.

Making more progress on AudioDispatchQueue.

A bit more progress on AudioDispatchQueue.

Making a bit of progress on AudioDispatchQueue; mostly just rearranging code.

Renaming AudioDispatchThread to AudioDispatchQueue and making progress on it.

Adding beginnings of AudioDispatchThread. The plan is to funnel all audio
calls for all clips through a queue, with a thread handling the queue. There
are five possible calls now, play(), loop(), stop(), pause(), and resume().
Without this sort of order the code is going to get extremely difficult to
understand and debug.
