Move most cinematic path simulation data and control from the graphics class to the simulation component and solve the hash mimatch in non-visual replay.

Move graphics code to smaller helper functions UpdateSessionVisibility,
UpdateSilhouettesVisibility and DrawPaths.
Remove the hotkey TODO code which should be implemented differently.
Mark voids as const.
