 * Requirements:
 *     MediaWiki 1.6.x+
 * Installation:
 *     1. Upload the `add-to-any-share-save` folder (and all contents) to your MediaWiki extensions directory so you have: `/extensions/add-to-any-share-save/`
 *     2. Enable the extension by adding this line to your LocalSettings.php:
 *            require_once('extensions/add-to-any-share-save/add-to-any-share-save.php');
 * Version Notes:
 *     0.1:
 *        Initial release. Add to Any is available for MediaWiki!
 * To-do:
 *     1. Have the <sharesave /> tag (functions below) additionally load the external JavaScript call before the </body> tag - please get in touch if you have any ideas on how to do this!
