Reorganised system ROMs out of the Mac-specific folder, adjusted Mac code to expect to find them organised hierarchically (as how many os.roms am I going to have?) and added readme files to explain what's missing from the Git repository.

Back to asynchronous updates and drawing, to try to improve guarantees on audio latency; experimenting with whether other parts of the approach are fundamentally flawed; added a broad-phase for scheduled updates on the 2600.

With no regard to performance whatsoever, endeavoured to bring sound to the 2600. It's very scratchy, so something is wrong.

Finally started on generalising the C++ stuff so as to be able to be able to get a working audio binding on the OS-specific side without further repetition by factoring an appropriate protocol out from the Electron and sketching out the correct speaker class for the Atari. Added a method to ask it what a good output frequency would be.

Added: key states are all cleared if the window loses focus. Which resolves sticky key issues. Allowing me just to use command+option+O for options and map both command and option as FUNC.

Spotted error was in texture target all along. This now gets as far as showing something a lot like the correct display, but precision is way off. Way off.

Switched key that maps to FUNC from command to option. Logic is that command may frequently be used for performing an action which changes the key window, in which case we won't realise if it is released.
