Get closer to what Icecast does (or will) expect wrt used codesets. I still

disagree with the new ISO-8859-1 assumption for non-Ogg streams, because
(for example) with ID3 tags, a codeset is simply not part of the specification
and a better assumption would be that they are in the user's locale.
Therefore, it would make more sense, IMO, to clearly specify that ANY metadata
sent to Icecast should be UTF-8 and let the source client figure out the rest.
This would also answer the question what codeset an /admin user should use if
the content type of a mountpoint isn't known (although that can be figured out
with an unclean read of the mountpoint's stats beforehand.)
