Add the ability to replace the source data file in Item_Model::save().

Refactor the rotate code in Quick_Controller to replace the data file,
and then have gallery_event::item_updated_data_file() pick up after
the change is saved, rebuild the image and handle album covers.  This
is much more portable than before and it will allow any mechanism (eg:
REST) to replace the source image.
