/*The following 'addLoadEvent' function allows multiple "window.onload" events to happen from multiple sources 
IMPORTANT!: do NOT add an 'onload' event to any page's body tag, 
    nor call any fuctions via "window.onload", use the call shown on line 24 or 25.
This was found through Webstandards.org and is published at 
       http://simon.incutio.com/archive/2004/05/26/addLoadEvent.
It has been tested on tested successfully on:
- IE 5, 5.5 and 6 for Windows
- IE 5 and Safari for Mac
- Opera 7.5 and FireFox on Mac (which behave the same on Windows as well).
