2D Tutorial: Normalize Vector Before Reflect

[AristurtleDev]

Description

In the 2D Tutorial, the vector used as the normal for reflections for the bat is not normalized before reflecting. This can lead to a situation where a normal of (1, 1) creates an exaggerated reflection.

// If the normal is anything but Vector2.Zero, this means the bat had
// moved outside the screen edge so we should reflect it about the
// normal.
if (normal != Vector2.Zero)
{
    _batVelocity = Vector2.Reflect(_batVelocity, normal);
}
