first pass of rotation sub-menu on images. It only posts on Image. For each selection it turns thumbnail gray, overlays a centered color spinning wheel, posts to the f/e to create a rotation job, gets the job id back, keeps checking the f/e to see when the job id is done, and when it is (for now) undoes the spinning wheel/grayscale - will return new thumb once done and pa_job_mgr has no code to handle job as yet
