[Icecast] listener authentication for multiple mountpoints

[Joel Ebel]

So here was my other question that got missed.

I just want to us the same passwords for two different streams.  I'm 
also curious if this is in any way related to clusters or grouping 
mentioned in the new features of icecast 2.2.  I don't think it is, but 
I can't find any good documentation on what clusters or groups are, or 
how to use them if I wanted to.

Thanks,
Joel
