Difference between 2.1 and 3.0 versions

[pavlovweb]

Small bug:
While parsing

    $vcard -> url 

it returns an array like

Array(
 '0' => Array(
                '0' => URL  
          )
);

if it is vcard of 2.1 version

and if it is 3.0 it gives a different result, such as

 '0' => Array(
                'Value' => URL  
          )
);
