Get 403 SignatureDoesNotMatch when path is encoded

[jamshid]

Change the example to test filenames that are encoded, such paths fail with 403 Forbidden - SignatureDoesNotMatch.

    objectName = ['myfile.txt', 'my+file.txt', 'my%20space.txt']

The object name should not be quoted, it should be added as-is:

        # add the objectkey. even if it doesn't exist, add the slash
-        buf += '/%s' % urllib.unquote(objectkey)
+       buf += '/%s' % objectkey

Looks like that fix was in #3 but for some reason it got reverted.
