[Simian]
* Avoid remeshing whenever possible by reverting back to using the untransformed mesh for the world mesh generation
* Add forceMeshing and forceTransform booleans to SimulationObject to specify when a new untransformed mesh needs to be generated and when the transformation needs to be reapplied
