added ability to auto-rotate jpegs as we import them. The auto-rotation uses /usr/bin/exifautotran which rotates losslessly, and we optimised to then not also re-rotate the thumbmail. This address a few bugs in the 90s, including the one where Mandys photos were not getting faces (they were rotated), and without really doing anything the odd one where we sometimes lost tmp_locn on first load after db recreation - I cant reproduce so ignoring it

     * run_ai_on throws log line, for matching even if there are no faces, would be less noisy to not do that (or should say no faces?)
