fixed a bug in "docs/glnames.py" which caused he generation of an
invalid Mac names table in the file "src/psnames/pstables.h".
This caused FT_Get_Glyph_Name to return invalid glyph names
for certain TrueType fonts..
fixed the PSNames -> Unicode translation table
the Python script "glnames.py" was buggy and
lacked quite a few values in the "names_to_unicode"
table !!
