[PATCH] Ogginfo utf8 conversion for mp3 plugin

[tom1 at toms-cafe.de (Thomas Günther)]

Hi!

Here is a patch that converts ogginfos from utf8 to the setup charset.
It is tested with mp3 plugin 0.9.15 and mp3ng plugin 0.0.9a. The cache
file /video/id3info.cache (or /video/id3info.dat for mp3ng) has to be
removed.
