Wrong encoding type in ListBucketResult - should not be url-encoded

[nanawel]

The library returns the value inside <Key> (= filenames) as a URL-encoded string, even when no content-encoding=url has been specified in the request. Moreover, no <EncodingType> node is ever present in the <ListBucketResult>.

The official PHP SDK fails to deal with this situation and ends up using url-encoded strings as simple UTF-8 strings which obviously fails later on.
