YH820: game fix and improvements

* sudoku: make colour icons (without screen was squeezed)
* jewels: add colour bitmaps
* pegbox: make game fit on screen (add small header bitmap),
  improve keymap

I left the original pegbox keymaps for samsung's YH-92x,
because they seem to make some sense there (YH92x has a
REC switch instead of pushbutton).
Someone with a YH9xx target has to check what is better...
