Title: Changes to tank movement and shooting

* The tanks now behave the same way as the old tanks game (90-degree turns)
* Direction keys also behave the same as the old game (left goes left, right goes right, up goes up, down goes down)
* Shots are throttled to once every second
* Holding the spacebar key will keep the tank shooting out bullets
