* Expose a client_throttle_multiplier setting in OpenSim.ini. This multiplier is applied to all the client throttle settings received by the client

* This should probably be 1, but currently by default it is 8, to reflect what was being eon3 in OpenSim before this revision.  So if the client requested a maximum throttle 
of 1500 kilobits per second, we would actually send out 1500 kilobytes per second
* Adjusting this multiplier down towards 1 may improve your OpenSim experience, though in other situations it may degrade (e.g. if you're using a standalone over high bandwidth 
links)
* This is currently a user setting because adjusting it down may currently reveal other OpenSim bugs.
