Added session identifier property to RKClient. RKClient now explicitly sends the session identifier in the request.

Previously the session identifier was automatically taken from the
cookie store, now we store it ourselves, and add it to the request
cookie header field manually. This fixes problems with
NSHTTPCookieStorage.
