status-json.xsl produces invalid output if field contains only "-" and optional whitespace
When my track hasn't title in tags, Icecast shows - instead of a blank line,(I suppose this status sends the client, mpd in my case, to Icecast server) so, I get json like this (see example) and this json isn't valid because "title" : - instead "title" : "-" . I checked it here - http://jsonlint.com/ So, I cant't do json_decode(), function returns null

}This is example of json, as You can see in first case I have title: - because of it I can not json_decode.
There is file xml2json.xslt from Doeke Zanstra https://github.com/doekman/xml2json-xslt on server. This file, I guess, convert xml to json and maybe there is a way to add new rule to convert - to null in blank title line, but I don't know how I can do it.
