Provides the proper framework for encapsulation of analyser target specifics.
... while making them a safe container for objects too. Uses the ZX80/81 as the pilot platform.

Eliminates diamond inheritance of KeyboardMachine::Machine by typers.
Specifically by pulling the key action stuff into a purely abstract class [/interface]. Takes the opportunity to unpublish a bunch of machine details.

Completes clean-up of post-formalisation per-machine keyboard code.
At least for now. Standardising on how column + row is encoded might be helpful.

Arranges for the ZX80/81 to get a peek at target configuration prior to construction. I'm as yet undecided on whether to make this the norm.

Formally declared the ZX80/81 and Amstrad CPC as keyboard machines in their public interface. Which means not having to repeat the meaning of set_key_state and clear_all_keys. So: a minor DRY improvement.

These should actually both be in the public header, as the types are used in an exposed method.

Reinstated typing ability, albeit with an ugly inline insertion. But I think I can defer dealing with typers to another pull request. The whole issue of keyboard mapping probably needs reappraisal.

Standardises on const [Half]Cycles as the thing called and returned, rather than const [Half]Cycles & as it's explicitly defined to be only one int in size, so using a reference is overly weighty.

Brought Typer into the new run_for orthodoxy, making it easier to clock consistently regardless of unit. Which necessitated adding a negative operator for WrappedInts.

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.

Decided to follow through on Cycles and HalfCycles as complete integer-alikes. Which means giving them the interesting range of operators. Also killed the implicit conversion to int as likely to lead to type confusion.

Introduced an explicit record of whether a video byte is latched. It's definitely incorrect to treat the latching of 0 as equivalent to no latching, as the byte that will eventually become video is not strongly implied.

Got to outputting something to the CRT. Should be just proper syncs and a paper background. It's not synchronising properly, so something is amiss in my timing.
