Optionsschalter vereinheitlicht, .sh-Skripte von überall aufrufbar

- gleiche Aufgabe = gleicher Schalter in allen Programmen:
  -c/--config (Alias --cfg), -i, -o/--outdir, --section, --format,
  -f/--force, -j, -t/--test, -y/--dry, -v
- svgconvert: -o statt -s (Alias --svgfolder), --section statt --format
  für die Sektion (Standard png), --format überschreibt das Bildformat
- webscan: --timeout und --browser nur noch lang (kollidierten mit -t/-b)
- glyphextract: -i nimmt Glyph oder Font, -e extrahiert (statt -f/-t)
- setenv.sh ermittelt das Projektverzeichnis selbst, alle .sh laden es
  relativ zum Skript; extract-font/fonttest reichen weitere Optionen durch
- Hilfetexte korrigiert, doc/README.md: Abschnitt "Gemeinsame Optionen"
