Subject: Improved the multi-song XMI support - Allow selecting every
 individual song of the XMI file - Allow dynamic song switch without
 re-opening of a file - Fixed XMI2MID converter with adding an ability to
 export every individual song - Added hooks for loop start and end events -
 Added an option to immediately stop the song processing on loop end reaching
 (needed to perform dynamic song switch at the loop end point)
