1. Rename kaa.notifier mainloop control:
   kaa.notifier.init() is kaa.main.select_notifier()
   kaa.notifier.loop() and kaa.main() is now kaa.main.run()
   kaa.notifier.step() is kaa.main.step()
   kaa.notifier.shutdown() is kaa.main.stop()
   kaa.notifier.running is kaa.main.is_running()
   kaa.notifier.signals (shutdown/step) are now kaa.main.signals
   
   kaa.main can be accessed by importing kaa, you can NOT import
   kaa.main directly.

2. Move kaa.notifier classes and functions into the kaa namespace.
   E.g. kaa.notifier.Timer is now kaa.Timer. No part of the code
   should use anything from kaa.notifier.

   Note: Exception for this is kaa.notifier.url right now

3. Renamed ThreadCallback to NamedThreadCallback and make the first
   paramater in __init__ the thread information (name or list of name
   and priority). The register function will be changed to __call__.
   The NamedThreadCallback is not InProgress object anymore, it is a
   Callback. In most cases ThreadCallback was not used directly so
   this API change should not break some code.

4. Renamed Thread to ThreadCallback. The class has no signals anymore
   and the start function is now __call__ and it will return an
   InProgress object.

5. Rename exception_handler in InProgress into exception and the
   exception callback function to throw. Add a convenience function 
   connect_both. The member variable is_finished is now a function.
