photo toolkit upgrade for the site

Now that I'm on a host that supports the common website toolkits, I've started turning them on for Gracevideo. Today I enabled the ImageMagick imaging toolkit. This should provide better quality preview / thumbnail images than we have had previously. It shouldn't cause the images to be radically larger, but perhaps a tad bit. There are several options I have not enabled (such as sharpening) and I may toy with those later. For now, we should have better images on the site when they are resized to fit.
