[ODE] Interact with a Object

Change the code about your drag & drop code to use addforce in order to change
the object's coordinates. It will then have all the information it needs to
calculate the velocity. But be aware that this will make your object movement
like a rubber band, which means that interaction is less direct. You could also
try to set the velocity of the body when changing it's position, but I read that
this might create instabilities in your simulation. Calculating the velocity can
be done by dividing the difference vector of the movement by the time, if I
haven't overlooked something.
