"Fix" for [#17671] Particles spin out of control and pass through when hitting collision object

-The fix is that particle random size factor should never ever be bigger than 1.0, else negative sizes are possible! Don't know who to blame, but probably my self :)
-The second issue of passing through the deflection and rotating wildly around strange centers is not a bug, but for particles the group and object visualization objects have to be centered on the global origin. I'll probably make an option later to use the object center, but this is how things are for now.
