    Improve the visual appearance of the devtab toolbar
    
    Improves the visual appearance of the Devtab Grid Toolbar by
    making the toolbar a linked widget with the Devtab Grid above.
    This prevents the odd visual look currently where the buttons in
    the toolbar have squared-off corners on the insides, while
    maintaining the UX-based separation of the 'delete-partition'
    button (which is destructive) from the other buttons.
