Original tracks should be preserved even if a music track is specified

At the moment we (re) combine the voice track and music track at the final stage.
This assumption is correct if we want to publish the result immediately.

But for some video's I've been wanting to do some additional editing. To do that I need to have access to the orignal voice and music track so I can decide what to do with that.

At the moment the workaround is simply using ffmpeg to pull out the music track from the original video and re-import this in blender.

Having it in the output file maybe more convenient? Since there is a workaround this isn't a really high prioirity for me.
