Removed initialization of XmlSerializer from abstract class (from XmlPacketTransmitter) to make mono happy.
* Fixed Graph.addEdgeToVertex to properly add (replace based on other vertex id) edges.
* Obsoleted Graph.AddValueToEdge since it wasn’t working and addEdgeToVertex is doing the job anyway
* Fixed percept handling so that a seen edge is only inserted into the world if it does not already exist with with a value
