Computing movement amount from framerate

Browse source 
Depending on the amount of power a computer has, the framerate will not be the same.
Hence, the amount of movement of a user should be constant on each frame.
If a frame was slow to print, the movement should be higher to keep a constant speed.

This PR takes the framerate into account when moving the players.
