Warning added to wxd2lat
The wxd2lat program now shows a warning when the -d option is used to produce a
document and a non-LaTeX text label containing non-ASCII characters is found.

Documentation bugfix
When renaming the former bmpp program to bitmap2pp the change was not applied
to the help texts shown by the program. Now "bitmap2pp --help" and "bitmap2pp
--manual" show the correct program name.
