using bit in pd->flag to signal the use of deformed rather than wasting pd->pad
removing evil cast
replaced by using convertToDispListMesh() ZR: I hope that's OK that way
commented off the ( debug purpose ) recursion trap in SoftBodyDetectCollision()
replaced forbidden okee() with printf() in there
( not so nice, since it does not anounce crash on UI )
note: crashing example from previous commit
needs enabling 'UMS' on panel to crash again
UMS = uses modifier stack
