- fixed 3147036 -- words separated only by newlines are getting rammed together on XML page
	- fixed 3147032 -- preformatted text is missing much whitespace on XML page

        * khtml/xml/xml_tokenizer.cpp: (XMLHandler::characters): Don't try to strip whitespace at all,
	because it needs to be in the DOM.

	- add support for more MIME types

        * khtml/khtml_part.cpp: (KHTMLPart::begin): Add "application/xml" and "application/xhtml+xml".
