old parser has been stripped from the old preprocessor-code which
  cleaned up both resource-scanner and -parser.
- Standard defines have been introduced (see README.wrc)
- Both preprocessor- and resource-scanner have been optimized slightly
  so that no backing up is required (one char lookahead is enough).
- Filename-scanning has been cleaned up, though not perfect yet.
- User-type resources are compatible now.
- Line-continuation in strings is corrected so that it does not
  introduce a newline in the output.
