Log:
* Introduced observer and observable interfaces for asynchronous events.
* Refactored the authenticate and distribute service to facilitate asynchronous
events.
* Removed Frame::WaitOnResult(), because frames are never confirmed directly.
Instead they are confirmed indirectly by an event != timeout event.
