Always also fly upward if you jump

So, at first I was super confused because the guy just didn't fly upwards, even when pressing jump! Turns out moving left and right had precedence and completely cancelled flying upwards. I think flying upwards should have precedence.

Also, I thought it might be fun to allow a bit of control when flying upwards, that's why I also allowed the JETPACK_STRAFE_SPEED to have a bit of an influence. You guys know the game better than me, of course, so we can also adjust / remove the influence.

From my play testing just now it seems considerably easier now, because you get sqrt(2) times velocity increase when pressing two buttons at the same time. The controls do feel a lot more logical now though. I would thus suggest to either drain fuel faster when two buttons are pressed/drain fuel based on velocity increase, or generally reduce fuel that the player has for a cheap solution. I could very well be very biased though, because I played the game too much :D

Yeah, I also thought about draining fuel faster 👍
