[DCP-o-matic] DCP-o-matic 1.69.0 released

Hi all, This version includes: * Various translation fixes, including a new translation to Dutch from Theo Kooijmans. * Fixes for a number of bugs, including: - failure to create KDMs (and bad initial start-end dates in the KDM dialog) on OS X. - lack of internationalisation on OS X. - glitchy subtitle display in some cases. - broken calculate-audio-gain option. - glitches in the colour conversion dialog on OS X. - bad rounding of timecodes in some cases. - an error on creating 0-audio-channel DCPs. - crash on trying to use DPX files. * Allow specification of the video frame rate that an audio file is synced to. * Add option to give left and right eye content separately for 3D. * Removal of some of FFmpeg's filters that don't work with image bit depths greater than 8 bits per pixel. * Allow up to 500MB/s JPEG2000 bitrates. * Improvements to the behaviour of the view's position slider near the end of films. * A tidied-up configuration dialogue, especially on OS X. * Auto-saving of film metadata before starting a DCP encode. * Some incomplete and clumsy attempts at allowing download of server certificates for KDMs. Thanks to Gérald Maruccia, Adam Colt, Thierry Journet, Theo Kooijmans, Max Aeschlimann, Andy Neddermeyer, Manual AC and Matthias Damm.
