release Vehicle Trader - DLC vehicle buy restriction

[El' Rabito 164]

If you don't own the DLC you can't buy the vehicle. Prevents inexperienced players from buying DLC vehicles by mistake.

 

1. Make a CfgExileCustomCode override for ExileClient_gui_vehicleTraderDialog_event_onPurchaseButtonClick.sqf with the following code.
> This only works if you use default classnames, if you use your own custom classnames it wont work properly!
