Add CSPlayerController.GetCameraEntity()

[girlglock]

Adding CSPlayerController.GetCameraEntity() would allow for modifying the cameras positions and angles without needing to teleport the entire pawn

this would also solve the issue of teleporting a player and them having their pitch all messed up until the first camera update like it currently is

we could independantly teleport the pawn with the position and velo, then teleport the camera entity with only the angles to properly set the pitch
