    raitv: Work-around leading linefeed at start of XML
    
    1. Open grilo-test-ui in terminal
    2. Rai -> Most Popular -> Black and White.
    
    Entity: line 2: parser error : XML declaration allowed only at the start
    of the document
    <?xml version="1.0" encoding="UTF-8"?><CLASSIFICAVISTI>
    
    Removing the leading linefeed fixes that problem.
