-----------
made correct physics visible on solver panel
i did not like the accusation blenders soft body module is too bad coded to not respect law of energy conservation.  
well .. animators most of the times don't care if there was a theoretical physics law .. they want to get things done 
hum i think 
on the other hand it is for sure raising confidence to the soft body module when simple physical rules can be verified
so i won't 'turn a hand' on either approach
IMHO the inaccurate soft approach serves best to animators 
anyhow 
you have both so you can decide devil or Beelzebub
have fun BM
