Added trading with animation skipped, complete salvaging for vehicles, lobby autoreturn upon death

Also trade from vehicle and backpack inventory. The later is kinda buggy so i would remove it. For it to work one need to add what each trader will buy in the TradeFromVehicle/init.sqf.
I've put everything in a custom folder with compiles.sqf (which is a copy/paste of mine so it needs editing maybe) not being sure on where the dayzcode used is changed.
