 - image-plugin: Replaced unicode characters in the crop buttons with images to fix display issues within Internet Explorer 7.
 - core: Fixed problem where Internet Explorer 7 and jquery.store will not work with frames since it will fallback to window.name storage. We'll now use a void storage for IE7. This means that IE7 will not be able to store floating menu postion and other settings.
 - core: Fixed problem of Internet Explorer 7 crashing when invoking jQuery's `removeAttr`.
