Fixed SetFloatFixed using the deltaTime parameter instead of the dampTime parameter in the dampTime field. Reduced 'speed' and 'vehicleSteering' dampTimes since they became pretty slow - since all the parameters have been using deltaTime instead of the actual dampTime since 35700 this wasn't visible before. This bugfix fixes the glitchy animations on players holding guns in demos, although that seems to be partly related to another bug where demos are running around 4% slow.
