New in 0.13:

• A lot more accurate looping (both full and regional loops)
• Added a 'two-five' to Exercise 053 (V7/III) and made a sequel for it (053b)
  
• Introduction of .sge files that hold information on what part of the audio file to use as an Exercise backing track (see the updated HowToCreateExercises.pdf in the attachments of this post)
• Slight sound tweaks to Exercise audio files (don't worry, the essence of cheap elevator music remains)
• Minor bug fixes
