Updated/added layout drawfiles for all Ursula layouts.
Ben Avison authored
Alt-Delete now does nothing (matches behaviour before it was definable).

Added "dialling codes" for Wales (1222), Wales2 (2222), DvorakUK (9944)
and DvorakUSA (991).

!IKHG.Chars files now use quoted characters instead of codes. This requires
the alphabet to be correctly set before viewing, but makes visual
inspection more reliable.
