* This finishes the ODE options section of the OpenSim.ini.example. I've added 44 configurable options!

* This includes if you want to mesh sculpties and the Level of detail on the sculptie meshing for non physical and a separate LOD on physical sculpties.
* The options range from gravity..  to avatar movement speed, to friction management..  to object density.. to update throttling.
