Change default option to enter/exit a vehicle

[fart1232]

So there is this bug where the default option for entering and exiting vehicles is enter and this means you cant enter a vehicle quickly or while either being able to move or being able to move the mouse. Needing to change it whenever someone new buys the game is probably not the best especially when they don't know what shortcuts are important to keep and the need to change it only arising in their mind after it kills them 5 times in the opening campaign missions.

Probably needs fixing asap.
