SyncPlayer 1.6.9 - type an alignment offset

Added

• Offset field in the Master row: type a known delay between the two videos and press
  Enter to apply it. Accepts seconds (12.5), a timecode (1:05), a comma decimal (0.5) and
  negatives (-3.25); positive means the reaction is ahead of the movie. It moves the
  reaction immediately and is remembered for that movie/reaction pair.

Fixed

• A leading minus was dropped when parsing the offset, so negative offsets behaved like
  positive ones.
