	<rdar://problem/3720111> REGRESSION(125-152): map fails to load depending on banner ad; weather.com (works in IE and Firefox)

        * khtml/html/htmltokenizer.cpp:
        (khtml::HTMLTokenizer::begin): Initialize currentPrependingSrc.
        (khtml::HTMLTokenizer::scriptHandler): Store a pointer to the currently
	active prependingSrc variable on the stack, the better to handle weird cases
	of scripts writing out additional script tags and so forth.
        (khtml::HTMLTokenizer::write): Deal with the above.
        * khtml/html/htmltokenizer.h: Declare new member field.
