Add Towtruck needed function.

benefits: when police have arrested a suspect and the vehicle is placed at a location that disturbs the road flow, police can call for TT to remove the vehicle.

I dont mind if its not 100% correct to IRL, but would atleast be nice to call it in to dispatch and a towtruck moves towards the vehicle picks it up auto, and towtruck and vehicle gets deleted after 200 feet from the player.
