Description:
------------
Exception::getCode() should return an int as per the documentation. Therefore 
SoapFault::getCode() should return the http code.

If you make a soap call to the deprecated Amazon Web Service 3.0 wsdl, a html 410 
(Gone) error is returned. SoapFault::getCode() and SoapFault::faultcode should 
both be 410, but they are HTTP.

Test script:
---------------
<?php
$client = new SoapClient('http://soap.amazon.com/schemas2/AmazonWebServices.wsdl', array('trace' => true));
$request = array(
        'keyword' => 'Stuff',
        'page' => '1',
        'mode' => 'books',
        'tag' => 'you\'re it',
        'type' => 'medium',
        'devtag' => 'YOUR-TOKEN-HERE'
);
try {
        $client->KeywordSearchRequest($request);
}
catch (SoapFault $ex) {
        if ($ex->faultstring != 'Gone') throw $ex;
        if ($ex->getCode() != '410') {
                echo "UnexpectedCode: " . $ex->getCode();
                throw $ex;
        }
}


Expected result:
----------------
 Nothing

Actual result:
--------------
