codecs: prefer libmad over libmpg123

Someone on the internet once told me that MAD is the best mp3 decoder
(and better than mpg123), so he must be right. I used to force mad in
my config file, but now I'm annoyed by the line "Forced audio codec"
that goes along with it.

Because I think that message is necessary and needed to discourage
users from doing stupid things, but I still want to get rid of this
message, I'm simply moving MAD up in the codec selection order.
(Please look away.)
