[NTG-context] Inkscape command line arguments have changed

[Thangalin]

Minor correction:

\startluacode
figures.programs.inkscape={
  command="inkscape",
  pdfargument=[[
    "%oldname%"
    --export-dpi=600
    --export-type=pdf
    --export-filename="%newname%"
  ]],
  pngargument=[[
    "%oldname%"
    --export-dpi=600
    --export-type=png
    --export-filename="%newname%"
  ]],
}
\stopluacode

Still doesn't work, though. ConTeXt persists with using --export-pdf=...
Cheers!
