Title: Fixes a memory leak with each AFKissXMLRequestOperation that uses responseXMLDocument

AFKissXMLRequestOperation has an instance variable called _XMLDocument, which it releases. However, the @property is @synthesized to _responseXMLDocument, which is not released. This results in a memory leak for every AFKissXMLRequestOperation for which responseXMLDocument is used.

The fix is to change either the instance variable name in the header and dealloc, or change the @synthesize to target the actually used name. I picked the former, as the name is (I think) better.
