remove last remnants of rotate instead of transform, updated rot* svgs to have arrow point in direction of actual rotation, AND, fixed bug where when we rotate an image that has already had an exif_transform on it, then we have to do that and then the requested rotation - fixes why sometimes we rotate say 180 when we intended a 90 rotate. Also, when we transform, recalc md5 as file has changed
