5 second pause by default after every file

[eerkatoka]

This should be on by default partly because it would help deal with malformed files when looping autoplay is on. Good feature to have anyway. Opt-out and adjustment of pause delay should be on settings.

This should definitely not be a default feature. Most people play tracks with silences at the beginning and endings of their files, and are quite happy with the fact that VLC jumps to the next track immediately. It does however seem like a useful optional feature, so I added a ticket for it to be picked up later.
