[DCP-o-matic] DCP-o-matic 1.81.0 released

Hi all, DCP-o-matic version 1.81.0 is now available from: http://dcpomatic.com/download This release includes: Updated ru_RU translation from Igor Voytovich. New pl_PL translation from Marek Skrzelowski. Updated fr_FR translation from Thierry Journet. Allow audio from different content streams to be used together in the same DCP (#274). Set the default colour conversion slightly more intelligently depending on content type (#565). Adjust colour conversion interface so that it's easier to use a preset. Be more strict about what characters are allowed in DCP names. Adjust job view in various ways (fixing #578). Fix hang if you cancel a paused job. Fix for distorted audio in some cases. Slightly improve performance with high speed encoding setups. Use j2c_<uuid>.mxf and pcm_<uuid>.mxf for picture/sound MXF filenames (#336). Fix for failure to analyse audio or create DCPs with negative audio delay in some circumstances (#571). Fix for failure to import video MXFs in some cases (#566). Fix for crashes when using some colour conversions which result in out-of-range XYZ values. Fix for failure to encode 3D from separate folders of images in some cases (#634). Thanks are due to Carsten Kurz, Marek Skrzelowski, Thierry Journet and Igor Voytovich. With best regards, Carl
