Title: Allow replaygain changes during playback

We have code to smoothly ramp replaygain changes,
so it's ok to update the value. (Most likely the user
is still cueing a track so applying replaygain value
is preferred anyway)

This bit me while I was loading new tracks, I had happened to start playing a track before analysis was complete, so I thought replaygain had failed.
