Title:			footnote printing

Blog post: 	http://blog.vicompany.nl/printing-links-better-with-jquery 
Comment:		Added and modified by Charlie Morris on 9/13/2011
				I changed the thisLink variable so that it grabs the whole URI, not
				just the relative link.  I also addded the ability to ignore certain
				anchors with the class "ignore"
