Upgrade to Spring Web Services 2.2.1.RELEASE

This commit updates the version of Spring Web Services to
2.2.1.RELEASE. The fix for SWS-892 means that in the event of an
interceptor failing to handle a request, the request is no longer
sent. The interceptor in UriVariableTests has been updated to return
true, indicating that the request has been handled and should be
sent.
