90856a0e7a Adds mixdown/up capability to Speaker.
To deal with occasions when the host machine just always is either mono or stereo, and the emulated machine must cope.

89d6b85b83 Adds optional stereo output for the AY.
The real chip provides the three tone channels as separate outputs, so a variety of different mixings can exist.

bf6bc7c684 Adds speed control into the SDL build.
If I can just figure out how to manipulate OpenGL from the timer thread to SDL's satisfaction, this'll be as good as it probably gets via SDL.
