[ui] Floating Tab Header mini.css

/*
    Floating Tab Header Mini
    With inline title enabled, it seems a waste to take up vertical space of the 'view header'
    especially if you don't use the back/forward buttons or the breadcrumb, so this minifies
    that interface into a float right toolbar.
