* Add FLAC export, based on WAV renderer * Depend on sndfile>=1.0.18 (previously >=1.0.11) * Add compression option to FLAC export, if available. The code related to compression is only generated if LMMS_HAVE_SF_COMPLEVEL is defined(libsndfile>=1.0.26). * Save into the correct file extension upon single-export. * Use unique_ptr in FLAC renderer and be more expressive about involved types. * Use unique_ptr and remove manual memory management in ExportProjectDialog * Add 'flac' format info to --help and manpage
