This creates a new `Fog::Core::Connection` class that wraps around HTTP connections/requests but does not presume SAX parsing of the API response. A new `Fog::XML::SAXParserConnection` is available which implements the original behaviour with a clearer interface. `Fog::Connection` subclasses `SAXParserConnection` to be backwards compatible. Further testing and deprecation warnings are needed. Since mock testing occurs at a higher level the changed code is not exercised by the tests and I do not have access to an XML based API to debug quickly with.
