///////////////////
// Thanks to Kevin Yank @ Sitepoint.com for the externalLinks function.
// It's a quick way to make xhtml compliant external links (target=_blank)
// It won't work w/ Javascript off-but those with it off are used to that
// and will know to use the 'back' button.
// I've modified it to allow other 'rel' types (popup,close,print)
