Christoph Oelckers 1f4594b450 - Duke: Only read keyboard input for movement when called for the actual tic.
Since the added values are not scaled, doing this per frame has the potential risk of achieving too high total velocity when combined with other means of input.
The change here was kept as simple as possible.
