Updated handling of inclusion timer.
Now handles inclusion events and stops the timer in the configuration handler if inclusion or exclusion is completed or fails.

Improved handling of include/exclude requests
Fix error queuing packet to stop inclusion/exclusion
Remove sending of 'inclusion end' message within inclusion handler.
This is now handled within the client, from the event handler. This allows the client to handle the error better, and also handle other reasons for stopping inclusion.
