Title: Authentication fixes (issue #35, issue #37)

* self.requests cachePolicy changed to
NSURLRequestReloadIgnoringLocalCacheData (issue #35, issue #37)
* caching of authentication credentials can be controlled via property
credentialPersistence (issue #35)
* connection:willSendRequestForAuthenticationChallenge: sends
credentials only once, then continues without credentials to trigger
NSURLErrorDomain error 401 (issue #37)
* cacheMemoryCost can be set to 0 to stop memory caching.
