    panelMenu: Use a normal St.Bin to allow styling
    
    Currently we don't add some style to ButtonBox like padding etc, we add
    it programatically taking into account minimum padding and natural
    padding. The thing is that with natural padding it works as expected
    even for low resolutions.
    
    As a design request, we need to style from css, and since the current
    ButtonBox class doesn't add any worth functionality, change that and use
    a simple St.Bin that allow normal styling.
