Playlist track weight usability tweek

Issue Summary

Our Show Hosts are complaining about the Weight values starting at Zero versus 1. Many of them have their playlists on paper first and then transfer it. They find it counter-intuitive to add the fourth item in their playlist to the apparent weight of 3.

I have changed:

$weight=0;

to
$weight=1;

Near line 229 in the station_playlists.module

Just food for thought.

Thanks.
