    style-scheme: tweak builder-dark style
    
    I don't like that this is using the same "content-bg" color as
    the various treeviews and other ancillary widgetry. We need
    some more separation. This is an unscientific shade(0.8) of the
    content bg color and some tweaks to the grid pattern color.
