Simplifies initialisation procedure for all machines.
With the side effect of allowing every machine to try to load only the ROMs that it needs.

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.

Modifies the Vic-20 and C1540 to bring them into the realm of self-ROM fetching.
Hence enables Vic-20 support within kiosk mode as currently drafted.

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

Ensured that a virtual destructor is declared, so that the various automatically-generated real constructors get in on the action.

Sought: (i) to instruct the CPC that it should be a 664, not a 464, if given a disk image (at least until I have RAM paging implemented for a 6128); (ii) to support ROM selection within the CPC and allow paging in of AMSDOS.

Minor tidiness: included missing headers, and spaced out the ROM type and key lists for readability.

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.

Fixed key values, causing the new set of keys to work, decreased quantity of output and ensured that pixels appear in modes 0 and 2.

Added enough stuff to put the emulated Amstrad CPC in a state of knowing whether its '0' key is pressed.

As per my keenness for cleanliness improvements corresponding to my ever-increasing C++ ability: turned the Amstrad into something that a factory produces, allowing me completely to hide a bunch of implementation details.

Fixed multiplier: the dot clock I've used to instantiate the CRT is the pixel clock, not the character clock.

Created a 6845 class and started pushing data at it and clocking it. It doesn't currently have the concept of a bus but will do, hence the in-header implementation.

With a very basic stab at something a bit like the memory map (sans paging), execution begins.

Performed sufficient wiring to get to the point where attempting to load a CDT creates an instance of the Amstrad CPC and then fails only because the thing vends a nullptr CRT.
