Title: Collision Detection and Bullet

New base class Collidable
-New class Bullet extends Collidable
-Ship now extends Collidable and has been modified to not override functions unneccesarily
-Bullets and ship need to calculate the proper delta x and y based on heading, should be something like: deltaX = cosign(heading), deltaY = sign(heading)
