Title: Apply pngcrush to some of the images

Saves a few kb of filesize on all PNG images losslessly. See http://en.wikipedia.org/wiki/Pngcrush

Not that great a saving since caching is used on all of the images, but there's no reason not to do it. If anyone is interested I'll apply it to the rest of the images in the project.
