Allow the repair tool to repair and/or do damage when it's clipping inside a player/vehicle.

It's kinda janky that you can't just press it into things that you want to repair, especially since there's no feedback to tell you that you're too close other than the sound stopping.

The current model makes it more or less impossible to use offensively unless the opponent is perfectly still, and it's already difficult enough to sneak up on people, so I don't think there's any risk of it becoming OP
