Changed build structure and updated to InternationalKeyboard 0.41 / !IKHG 3.01 from trunk, thereby acquiring Windows 95 and Japanese key support, and made further changes, viz:

Fixed lastreadkey bug in !IKHG, added NOP so Int'l Keyboard assembles cleanly.
Added Welsh alphabet and Wales2 country support.
Switched Wales into and Russia2 out of build.
In UK layout, moved bullet from Alt-Shift-8 to Alt-Shift-\.
In Wales layout, added Alt-T = TM, Alt-Shift-Z = single left angle-quote,
  and Alt-Shift-X = single right angle-quote.
Fixed !IKHG to call key D16 "End" instead of "Cpy".
Merged PC-delete code and Ursula service call table back in from Ursula branch.
Added PC-delete compatibility to !IKHG.
Added Alt-E shortcut for Euro symbol as follows:
  * No further action was required:
      Italy, Norway, Esperanto
  * oe/OE moved to Q:
      UK, Spain, France, Sweden, Finland, Denmark, Canada, Belgium,
      Netherlands, Switzerland, USA
