[Icecast] Dynamic Playlist

Thanks Mike,

I'll look into the random/shuffle thing some more. It's not a big deal for
my NetJuke listeners, because for the most part they're defining their own
playlists. But for my peercast listeners, who don't have control over the
playlist they hear, it is a big deal. Every time I update/add to my
broadcast playlist (which is daily), the stream basically starts over. The
consequence of this is that no one ever gets very far into the playlist and
they get bored hearing the same stuff over again. 

Mark

First up: random is misnamed, as it's not intended to be truly random.
Instead, it shuffles the list: this means that normally, you can't hear the
same thing until it has reached the end of the shuffled list.

However, when the list is re-read, it's also re-shuffled.
restart-after-reread is correctly used, but does roughly nothing in this
case.

The shuffle should be completely random. If it isn't... there's a bug
somewhere. Perhaps your system does have a very random rand() function?
Perhaps we should use a better RNG  in ices.

You can hook this into IceS2 using the 'script' playlist module, but I don't
know if anyone has written an appropriate script to speak to mysql. I
haven't, personally.
