    chatView: switch away from deprecated API
    
    The chat view is currently using the selection background color for
    nick names. However as gtk_style_context_get_background_color() has been
    deprecated in GTK+ 3.16, use the foreground color for the LINK state
    instead, which should be identical for the default theme.
