Speculative change that will hopefully cause the namespace to 'web.xml' files to be maintaned when transforming. Will need a test added if it works.
#1037 - updating the commit made by @dchambers earlier so that it uses the documentBuilderFactory we've set namespace aware to 'true'
#1037 - Adding test which proves that the xmlns is preserved after building the war
- Spoke with @dchambers and even though we didn't see this fail when we backout the 'fix', it's still a valid test
- It may just be turning out that the XML processor used by the test depending on the service provider may respect the namespace and not clear it
