Log Message:
-----------
Bugfix: 32bit cloth files were loaded bad in 64bit blenders and the way arround. The e.g. GUI-only variable 'mass' was reseted to 0. Problem: makesdna doesn't cry out on compile - I wonder why this differences could happen. Solution: Rearange cloth DNA, resort things, clear up and bug was gone - weird. Problem left: Every file having cloth enabled before this revision is incompatible with this version. If anyone know a better solution, please go ahead
