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)
