Add debug mechanism for only sending 1 in N AgentUpdate packets to child agents.

Browse Source 
Allows experiments in manually reducing updates under heavy load.
Activated by "debug scene set client-upd-per" console command.
In a simple test, can send as few as every 4th update before observed movement starts becoming disturbingly rubber-banded.
