Cloth structure names update: Sorry about this commit, it will kill all your cloth settings in old files but I had to do it before release because naming convention was really bad in cloth (e.g. using SimulationSettings instead of ClothSimSettings in DNA). Same for some structure in CollisionModifier but with no sideeffects.
