Play sound when generation completes

[brknsoul]

lshqqytiger's fork in Windows played a sound if you had "notification.mp3" in the same folder as "webui.sh".

This doesn't seem to work for vladmandic's fork, at least in Ubuntu 22.

Also, it'd be nice if a small beep from the console (perhaps using the same file as above, since PC speaker is default blacklisted in ubuntu) could happen after the "Model loaded in ..." message to indicate the server is up and running.

Submitted PR #606 to re-add this feature.

Thanks everyone for this commit!

I am used to this feature in A1111, I would be very happy if you add it too.

Currently, the mp3 is pointed to html\notification.mp3. You can change this in Settings > Live Preview.
