Title: FB session delegate for relevant authentication events

Introducing a session state delegate to get callbacks about relevant authentication events like session state changes
`- (void)fbSessionStateDidChange:(FBSessionState)state;`
finished authentication
`- (void)fbSessionDidFinish:(FBSession *)session; `
and the receiving of the access token for our OAuth Client
`- (void)fbSession:(FBSession *)session didReceiveAccessToken:(NSString *)token;`
