Summary:
Rename README.KeyTab to README-KeyTab to prevent Konsole from trying to
load it as a keyboard translator file, and fix references to that file
name in other files.
Flesh out README-KeyTab and README.keyboard and reformat them.
Also copy the the original README-KeyTab to README-KeyTab-original,
just in case there's some concept that I misinterpretted/misunderstood.
