Switched definitively to the works-for-now approach of requiring an explicit opt-in where somebody wants to clock a whole-cycle receiver from a half-cycle clock.

Relocated ClockReceiver.hpp as it's a dependency for parts of the static analyser, and therefore needs to be distinct from the actual emulation parts.

Eliminated redundant uses of ClockReceiver and sought to ensure that proper run_fors are inherited all the way down.

The 6560 is now a ClockReceiver. This reduces to zero the number of remaining instances of the text run_for_cycles in this codebase.

Enshrined a default colour burst amplitude. Which now everybody relies on. The 102 figure is derived from the burst apparently being 40 IRE.

Settled definitively on flush as more communicative than synchronise (and slightly more locale neutral); culled some more duplication from the Z80.

Switched the 6560 to two bytes per pixel, since one isn't sufficient for precision and because mixing up the implementation might help me to figure out what's amiss.

It turns out that the Vic has a 1.6Khz low-pass filter. So added that.

Turned the 6560 into an ordinary template, similar to the rest of the project, albeit right now with a fairly shonky internal implementation. Fixed a Mac-specific interface sizing issue.

Converted the 6560 fully into a template; worked on allowing the typer to run at a much faster rate where hardware has some trigger by which it can request the next key.

Shunted code for the main part up into the header, in advance of turning it into a template so as to bring it inside the normal orthodoxy.

Advanced to having some characters displayed, even though they're obviously very much incorrect and the display is still rolling.

Without yet figuring out what vertical sync is meant to do, moved just about far enough forwards to see _something_ that hopefully I can soon discern characters within.
