Title: Added a filter for grayscaling

I have added a simple filter for grayscaling an image - nothing more.

Are you interested in more filters? In my session i also wrote an abstract filter which changes the color of a pixel based on an arbitrary matrix and it's neighborhood. With that, i implemented a filter for border detection based on the laplace-operator - likely not fast on huge images (like greater than VGA).
