- fix Cocoa window setOrder function to maintain focus on a blender window (e.g. ensure the blender window gets the focus when the user presses ESC to move back the render window)

- QuickTime export fixes.
Note that QuickTime export still crashes because it tries to open a "codec settings" dialog from the rendering background thread (and not the main/UI thread).
One quick fix may be to move the movie export initialization out of the render thread back into the operator function.
But a cleaner way would be to get rid of such a carbon/win32 dialog and place the codec settings inside blender interface
(additional fields in the output panel as it is currently the case for other file formats ?).
