[Flac] Replay-gain

Don't apply replay gain during conversion; there should be a checkbox in
foobar to enable or disable this option.  Replay Gain should only be
applied during playback.    See:

If you convert to MP3, you can calculate replay gain on them after the fact.

Just because Replay Gain information is stored in the FLAC file doesn't
mean the decoder has to use it :)
