Flight model

Got a basic flight model up and running. As the game will be heli-something based, I've opted for the classic LEFT, RIGHT and UP for thrust controls. Gravity will obviously control the downwards motion.

I want to get a tipping/leaning motion in on the player vehicle, where the nose dips downwards for left and right movements. This will hopefully make the vehicle feel more weighty.

At this point I've decided I'm going to cut corners with the player vehicle sprite, mirroring the sprites for the left and right movements.
