Various minor tasks!
- Move smStaticSceneObject to smSimulators folder
- Renaming required at many places: smDummySimulator, smContact, smMystylus, initCustom, syncBuffer
- Move smCollisionMoller source into utilities
- Extend/enlarge basic analytical geometric types such as smPlane, smSphere, smEllipsoid
- Move smTextureManager, smMouse,smGeometry etc out of smCore
- Make sure iterators are all pre-incremented. Post-increment results in slower code. As a policy we should require that all indexing variables (this include iterators) should be pre-incremented.
