Fix tilting in splitscreen

Browse source 
R_GetPitchRollAngle used R_PointToAngle. This was fine because it was meant for rendering code. However tilting does its code mostly in player thinker, and it also uses this function, so it was not fine -- it would have some remainder tilt settings from the last player's screen.
