Refactors `AudioFileOgg`, a class used to export to OGG files. There were problems reported of the exported OGG file failing to be played back on some systems. To fix this issue as well as to improve code quality, the class was refactored. In addition, VBR (variable bit rate) is always used, with the quality of the export being determined by a ratio of the selected bit rate and the maximum bit rate allowed. This change naturally occurred when refactoring, though the libvorbisenc documentation recommend VBR for improved audio quality.
