Offloads the action source on disk. The source storage must be set to external and the file must be valid. The source is saved and all current AnimationSourceItems are removed. All Clips that use the source are notified and are disconnected (the clip's color will turn gray) and the source icon in the explorer changes.
Note: Offloading is only available for animation and not for shape or audio.
