- add support for virtual fonts in virtual fonts
- font maps: treat font files without extension as Type 1 (to
prevent warnings occuring especially with Minion or Libertine fonts)
- fix UnicodeDecodeError for invalid character responses by TeX/LaTeX
(reported by Gert Ingold)

- removed underscore in PS and PDF and SVG writer options strip_fonts,
text_as_path, mesh_as_bitmap, mesh_as_bitmap_resolution
(new: stripfonts, textaspath, meshasbitmap and meshasbitmapresolution)
to prevent ambiquity with write_ prefixes.
