Within the `Typer` framework: hatched out `CharacterMapper` as a distinct thing from the target for keypresses, better to formalise responsibility but also to make it easy cleanly to sever that stuff into its own little part.

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

Transfers possession of keyboard mappings from the Mac side over to individual machines. Specifically by establishing an intermediate representation of a useful mix between the American and British IBM and Mac keyboard layouts, and routing through that.
