Feature request: Option to move demos upon completion

[NorskNoobing]

This is just a QOL feature, but it would've been nice if the container could have a temp-, and a demos-folder. The temp folder would work like the current folder, but it would move the file to a new demo dir on the Demo saved to file-, or probably more correct, the Demo save complete-event. Both of these events are already logged to the docker-containers logs.

It would help to know when the file(s) are finished downloading, and if you're using this container together with another service to scan/analyze your demos.
