tkemc: simplify worldlabellist, axiscoordmap
tkemc: simplify worldlabellist, axiscoordmap

since 4b9ca027 worldlabellist always held all the axis letters A...W and
the axiscoordmap was always 0...8.  The padding to at least 9 items
also became unneeded.

In this case, the initialization code can be greatly simplified.
