inconsistencies in status-json.xsl

[Yamakaky]

• If there isn't any sources, json.icestats.source is not defined
• If there is one source, it's an object
• If there is 2+ sources, it's an array of object

That makes it harder to handle that it should be. I suggest always generating a "sources" key as an array of objects (empty if no sources).

Also, I forgot to record it but at one time the generated json wasn't valid. Don't you wan't to use a json lib? It should solve this point easily.

This is not so easy to solve at the moment as the main and internally used format is XML.

The status-json.xsl was replaced by the publicstats interface. Therefore closing this ticket as it is about now legacy parts.
