Switchs XElement Be/NotBe checks to use DeepEquals

I may be wrong in my interpretation of this item, so please correct me if I am.  To me, it looks as though Issue #3 is a bug in which FA is giving false positives which seemed like something that would be good to correct.

Issue #3 linked a codeplex item in which there was some discussion of normalizing the XML.  This solution does not include normalization as I was not sure if is was necessary or the desired behavior.  Would be easy enough to integrate the normalization code that linked on codeplex if that would be preferred.  Though we should probably see if we can get Eric White's permission since I did not see a license indicated with his posted code.
