Only log output and write progress to db if it has changed

Browse Source 
De-noisify the transcoding log and db updates. Previously we would log
and save the progress percentage every second, even if it had not changed
at all. Save progress:oercentage in the Transcoder and only log/update
when the percentage has actually changed.
