Log Message:
-----------
soft body bug fix own finding
left overs from new particles
-wind and force did not work if aero or edge collision was activated.
-force field had flipped sign compared to particles
tsk who thinks a attractive force should negative sign? well... i am passionless with that.
-adapted effect of wind and fields on softbodies such that softbody "particles" and particle "particles" behave consistently
note! 
effect of wind is 1/25 compared to before   
other forces 1/10
