Small update for vehicle camera modes

[list] [*]Improved smoothness of smooth turning in first person decoupled mode vehicle camera. [*]Fixed 3rd person vehicle camera height not always being consistent when entering a vehicle. [*]You can now turn the camera in the teleporting vehicle camera mode; the camera orientation will no longer automatically reorient to the vehicle. [*]When driving towards the camera in the teleporting camera mode, it will now teleport farther apart from the vehicle so that you can see better where you are driving. [/list]
