/****************************************************************
 * Get browser info script.
 * created: 6-Aug-2009
 * author: Bsv
 * 
 * Tries to get information from:
 *  Navigator Object, 
 *  use ActiveXObject for IE pluggin detection, 
 *  makes calculation for connection speed
 * Has ability to send all grabbed information via default 
 * mail client
 * 
 * Input parameters:
 * 'html' - as result redrowDocument() will be called
 * 'form' - as result document.contact_form.info.value 
 *          will be populated
 * 'both' - as result - document.contact_form.info.value 
 *          will be populated AND redrowDocument() will be called
 * 
 * As result:
 *  info could be rendered on html page,
 *  could be passed to document.contact_form.info.value,
 *  could be send via default mail client
 *  
 * see methods redrowDocument()
 * and prepareInfo() 
 * 
 * Requirements:
 * 1. These div-s should be present inside html:
 * <div id="loadImage" style="position: absolute; top: -1000px; left: -1000px;" ></div>
 * <div id="content"></div>
 * <div id="loadDiv" style="font-weight:bold; color: grey; margin-top: 20px; text-align: center;">L O A D I N G ...</div>
 * 2. Body onLoad should call showInfo()
 *
