/**
 * Modalpreview (http://devkick.com/lab/modalpreview/)
 *
 * Modalpreview is a jQuery script that makes it possible to preview the textarea content in a modal window before submitting the form.
 *
 * Many blog readers prefer to preview their comment before submitting. It is always much easier to
 * check language, spelling and sometimes markup when looking at the text in HTML as if it was already
 * rendered on the site. Some software comes with a built-in preview function using a back-end 
 * reload of the form, and some comes with the optional plugin (ex. wordpress).
 *
 * Back-end previewing works well enough in most cases although it can be jumpy and slow
 * if the blog post is very long. As an alternative, modalpreview automatically adds a preview button
 * next to the submit button that brings up a modular window containing the textarea content, without reloading
 * the entire page. It converts line breaks to <br> and removes the <script> tag to prevent hacking.
 * Modalpreview can also strip HTML before rendering the preview.
 *
 * 
 *
 * Tested in Safari 3, Firefox 2, MSIE 6, MSIE 7, Opera 9
 * 
 * Version 1.0
