Copy vehicle customisations using deep copy

[NikkoJT]

Currently, if you copy a vehicle, using ordinary Zeus copy or Achilles deep copy, the pasted vehicle reverts to the default customisation options for its class (i.e. a black Qilin reverts to hex or Pacific hex).

It would be very useful if the Achilles deep copy allowed you to copy vehicle customisations. I think BIS_fnc_initVehicle should be sufficient to set the options on the new vehicle, although I'm not sure how you might retrieve the information from the existing vehicle.
