`html-parse-string' ignores script tag and comment.

[HAMANO Kiyoto]

I tried `html-parse-string' function.
Its feature is very interesting and very nice.
Thanks for implementing!

But, `html-parse-string' ignores script tags and comments.

(html-parse-string "<script>foo</script>")   ; => (html (head (script nil)))
(html-parse-string "<p>foo</p><!-- bar -->") ; => (html (body (p (text
. "foo")) nil))

The cause is like the make_dom function (src/xml.c).
The `make_dom' function see a XML_TEXT_NODE and XML_ELEMENT_NODE.
But, The function don't see a XML_CDATA_SECTION_NODE and XML_COMMENT_NODE.
Therefor, It seems that the script tag and comments are not displayed.
