    gutterrendererlines: remove pango markup usage
    
    Now that the GtkSourceGutterRendererText can handle the changes for the
    current line foreground color and weight, we no longer need to handle
    this from the GtkSourceGutterRendererLines.
    
    We can also save some time generating strings since we can always use the
    helper now. Not to mention the parsing of markup too.
