svgconvert.sh ruft svgconvert.py auf, generationlib entfernt

- bin/svgconvert.sh ist jetzt ein Wrapper wie svgconvert.bat
  (gleiche Optionen unter Linux und Windows)
- svgconvert.py: Endung .cfg/.csv bei -c/-i optional
- bin/generationlib (nur von svgconvert.sh benutzt) entfernt
- doc/README.md angepasst
