VoxelPacketProcessor -> OctreePacketProcessor

added nodes bookkeeping in ReceivedPacketProcessor; added check in
sendNack() to not send NACKs to nodes that have sent packets that are
waiting in the message queue.
added default constructor for NetworkPacket

updated param comments in ReceivedPacketProcessor
fix some bugs in models
moved sendNack() into packetDistributor()

...for the purpose of enforcing packets sent per interval in

special packets sent where sendSpecialPacket() was assumed to only send
one packet per call.
changed NetworkPacket::_sendingNode to ::_node
