Continuous collision detection

[mkhan45]

If the ball goes fast enough, it wont hit the paddles.

This can be fixed by checking if a paddle lies between the ball's start and end positions during a frame. Also have to calculate the position of the ball at the time of collision.

While we're at it integration should also use delta

it will still break down if it can go fast enough to bounce between paddles in a single tick
