annotate data/model/Model.cpp @ 348:edda24bb85fc

* Skip ID3 block when reading MP3 files (so long as ID3 support is included) * Show progress when retrieving audio file from playlist * Avoid -- but do not actually fix -- segmentation fault on exit. I am totally stumped at the moment about why both the PA and JACK audio targets should crash when properly shut down. For the moment, we just don't shut them down... * Fix incorrect behaviour (introduced on Friday as part of a different fix) when replacing main model in situation where no current main model exists
