    main: Update state of previous/next when chapters info arrives
    
    This fixes the previous/next buttons not being sensitive when a single
    file with chapter data is read as the "hey, a chapter is available now"
    would come in later than we usually check.
    
    The keyboard shortcuts for previous/next track already worked as whether
    a chapter marker is available is checked when the key has been pressed.
    
    Closes: #215
