    jQuery Cross Domain Ajax Plugin
    (c)2010 Martin Boynton - work in progress
    
    if the response is XML, use another plugin:
    $.loadXML(o.responseText)
    
    currently accepts:
        url:"http://www.google.com/"
        success:function(o){}
        error:function(o){}
        timeout:1000
