/*
 * Bugmenot.js: For Ubiquity Parser 2
 *
 * Thank you all for using bugmenot.js.
 * Thank you Heater Kofke-Egger for notifying me about parser 2.0 changes.
 * Also thank you Brandon Goldsworthy for updating this command.
 *
 *
 * This file has been modified from Onur Yalazi's original distribution
 * by Brandon Goldsworthy.
 *
 * Changes:
 *   Added a preview. The preview shows all of bugmenot's results,
 *     though execute will still only insert the highest rated one.
 *   Use current window location as default url for both preview and execute
 *   Add error callback to jQuery call to bugmenot's page.
 *   If not in editable field, opens bugmenot in new tab
 *
 * Onur's original attribution info is left in-tact below.
 * You can get his original file there.
 *
 *
 * Changelog:
 * 2009-07-16 Onur YALAZI <yalazi@mobilada.com> 
 * 	bugmenot-p2.js:  modified for parser 2.0
 *            		 added new synonym bmn
