Added documentation to RBAudioPlayer, and removed some useless code from RBPartyViewController.
NetAssociation now queries the server every 4 seconds, no matter what. Added ability to stopSynchronizingNetworkTime in NetworkClock. Some more refactoring of NetworkClock. RBClient no longer tells it’s delegate that it successfully connected twice. Refactored RBNetworkUpload to not hold onto the original NSData passed in, which should reduce memory usage while transferring data. RBPartyViewController stops synchronizing time when we disconnect from a party.
