Replace the timestamp based state system

Browse source 
This commit replaces the timestamp based state system with a new
one that has update channels directly to the connected nodes. It
will send an update to all listening clients via the polling
mechanism.

It introduces a new package notifier, which has a concurrency safe
manager for all our channels to the connected nodes.
