Default the selection to the given aspect ratio

For usability sake, I think it would be a good idea to offer a default selection when the image is displayed, after upload. Being that no cropping window is present, users can be a bit confused as to what should be done on the page. I myself, submitted the form a few times just be alerted that I needed to select a crop.

The attached patched defaults a selection of the aspect ratio, at the top-left of the image, by adding "setSelect: [cwidth,cheight,0,0]" to the #cropbox declaration.

Outside of the scope of this patch, you should no longer be using $(document).ready(). See the Drupal JS docs for more information or let me know if you need help.
