0.8.1b5

Fixed

• Boxes on the Live tab now always match the picture. While a check was still looking for
  objects and faces, the Live tab could show its new frame with the boxes of the check before — a
  person (and their face) drawn where nobody stood any more. A new frame now appears together with
  what was found in it.
• The face model is let go when face recognition is turned off while a check was still busy:
  that check could load it again, and it then stayed in memory until a restart.
