demo console: polled frames and the real stats field names

Browse Source 
The camera used an MJPEG stream through the proxy and the engine's
stats under names it does not use (frames/faces rather than
frames_processed/faces_seen), so the picture was blank and the counter
read zero. The engine re-serves its latest frame until the pipeline
produces a new one, so a polled still is the same picture with none of
the multipart fragility - which matters when the audience is in the
room.
