	Required files:
	* jquery.js (http://prototypejs.org)

	USAGE:
		PostLink(id, url, confirmText)

	EXAMPLE:
		<a href="/somewhere.php" id="mylink">Click to Post</a>
		<script type="text/javascript">PostLink(id, '/somewhere.php', 'Are you sure?');</script>

	1-26-2007	Fixed variable scope for referencing window.confirm()
	2-11-2007	Use Event.observe from Prototype
	2-11-2007	onclick function moves up from the Event.element() node to
				find the anchor element as necessary
	11-21-2007	Case-insensitive tagName checking to resolve discrepancies
				between HTML and XHTML
	1-30-2010	Modified to use jQuery instead of Prototype
