SoundClip can now fire a callback after a sound has completed being played (i.e. the duration of the sound has passed by). I have added an example of this with the scene music. [t:346]

{
	'opengl': ['core/video/opengl/', 'core/gui/base/opengl/'],
	'zip': ['core/vfs/zip/'],
	'script-python': ['swigwrappers/python'],
	'script-lua': ['swigwrappers/lua'],
}
