Add PERFORMER & COMPOSER metadata tags to audio tracks (if available). Composer(s) and performer(s) will be extracted from MusicBrainz recording metadata by new _getComposers and _getPerformers functions then there will be new properties added to each track metadata. If those data are present it will be tagged as new tags PERFORMER and COMPOSER.
