/**
 * External links Javascript, for XHTML strict external links.
 * How to use:
 * 1. Set rel attribute on all external link anchor tags to "external". Eg. <a href="http://www.google.com/" title="Google" rel="external">
 * 2. If desired, add class "new-window" to anywhere you want to add a new window warning. This means if javascript is disabled, you won't warn people about something that won't happen. Eg. <span class="new-window"></span> I recommend using an empty span for this as the element's contents will be replaced
 * 3. If desired, change warning_text variable below to the HTML you want to place between the tags defined in 2.
