April 2006 - Liana Thomas
* Changed footnoteLinks to take an array of IDs to traverse.
* Made a fix so that in IE images aren't counted. (checks that the 'href' and 'src' attribute are
	not equal which works because 'src' won't be set for non-image link tags)
* Changed classes from .printOnly to printonly and .ignore to .ignore-footnotes
