Title: Mode 1735 - Updated remove behavior involving federation

Several aspects were implemented/changed:
* removing federated nodes or their ancestors does not propagate all the way down to the connectors and the external nodes
* for a connector to get the _removeDocument_ notication, a _node.remove()_ has to be performed on an external node.
* added cleanup around the _federatedSegments_ section of federated nodes and in the system area which stores the projection mappings
* added a _FederationManager#removeProjection_ method which only removes a federated segment from a node, without affecting any of the external content.
