[Icecast] ices2 loop song

Hi,

I believe the reason for this is to do with ogg stream serial numbers. 
Apparently having identical serial numbers in sequential ogg streams is a 
violation of the ogg spec.

As I've posted before, there are legitimate reasons to stream the same file 
over and over.  There's also the point that if you're re-encoding, you won't 
be in violation anyway (I think), since the encoder would make its own 
outgoing stream.  So this particular feature is a bit questionable in my 
opinion.

Geoff.
