Standard theme border-radius on .generalbox

Test Instructions Navigate to Site Administration > Development > Purge all caches and Purge all caches View the div#notice element on the Purge all caches page, itself a div.generalbox, and note that bottom left and bottom right corners now have the same border-radius as top right and top left corners. Alternatively, navigate to Site Administration > Notifications; there are usually a few div.generalbox elements there upon which you can verify the change. Alternatively, view or create a Web page resource and then view the resource. The content is presented inside a div.generalbox. All corners should have the same border-radius.
