issue in status-json

Hey guys and girls, I have an issue with the json status output. We rely heavily on it for getting the stats.

When we have a service with multiple sources, the json script isn't outputting correct json. Look at the following example. The json['icestats']['source'] key contains an array of 3 sources. The first one is correctly formatted, but the next to have a surplus comma at the end, and are missing the closing curly brace.

I've looked at the status-json.xsl and xml2json.xslt files, but I have no idea where this behaviour is coming from.

Any ideas? Fixes?
