* Fixes the 10x10x10 hard physics limitation. (wierdly, you have to set this for each region in your Regions.ini[PhysicalPrimMax = 10(default)])

* Adds a configurable maximum object mass before the mass is clamped.  Default is 10000.01.  Configurable by changing maximum_mass_object in the [ODEPhysicsSettings] section.
* Clamping the mass is important for limiting the amount of CPU an object can consume in physics calculations.  Too high, and the object overcomes restitution forces by gravity alone. This generates more collisions potentially leading to 'deep think'.
