two fixes:

- while Faceselect mode on Subsurf, it didnt render the changes. this was
  because the displaylist wasnt updated (the 3d window shows original mesh)
- added proper redraw event for F10-sound buttons when you add a new sound.
  somehow sound doesnt play anymore here... have to check further.
