expand in the info raycast returns

Browse source 
This change will allow to get the position of a hit with raycast, the normal and the body, some extra info that otherwise you couldn't obtain because raycast only returns a body, this may break some compat but I think is better than having multiple functions that do the same logic only for obtaining each piece of information separated (to keep compatibility).
