Mostly HTML generation and parsing enhancements:

- HTMLparser.[ch] testHTML.c: applied the second set of
  patches from Wayne Davison <wayned@blorf.net>, adding
  htmlEncodeEntities()
- HTMLparser.c: fixed an ignorable white space detection bug
  occuring when parsing with SAX only
- result/HTML/*.sax: updated since the output is now HTML
  encoded...
