Chapter 1 / 6 error in comments

[Shadowblitz16]

Chapter 1 / 6 says ..

            // shader.frag has been modified yet again, take a look at it as well.
            _shader = new Shader("Shaders/shader.vert", "Shaders/shader.frag");
            _shader.Use();

when it should say...

            // shader.vert has been modified, take a look at it as well.
            _shader = new Shader("Shaders/shader.vert", "Shaders/shader.frag");
            _shader.Use();

This issue applies for 7-Transformations, not 6-MultipleTextures. I fixed it in a commit.
