	 * InstaView - a Mediawiki to HTML converter in JavaScript
	 * Version 0.6.1
	 * Copyright (C) Pedro Fayolle 2005-2006
	 * https://en.wikipedia.org/wiki/User:Pilaf
	 * Distributed under the BSD license
	 *
	 * Changelog:
	 *
	 * 0.6.1
	 * - Fixed problem caused by \r characters
	 * - Improved inline formatting parser
	 *
	 * 0.6
	 * - Changed name to InstaView
	 * - Some major code reorganizations and factored out some common functions
	 * - Handled conversion of relative links (i.e. [[/foo]])
	 * - Fixed misrendering of adjacent definition list items
	 * - Fixed bug in table headings handling
	 * - Changed date format in signatures to reflect Mediawiki's
	 * - Fixed handling of [[:Image:...]]
	 * - Updated MD5 function (hopefully it will work with UTF-8)
	 * - Fixed bug in handling of links inside images
	 *
	 * To do:
	 * - Better support for math tags
	 * - Full support for <nowiki>
	 * - Parser-based (as opposed to RegExp-based) inline wikicode handling (make it one-pass and
	 *   bullet-proof)
	 * - Support for templates (through AJAX)
	 * - Support for coloured links (AJAX)
