It's in this bit of code:

.navbar {
        position:relative;
        height:{vb:math {vb:stylevar navbar_tab_border.borderWidth} + {vb:stylevar navbar_tab_size.height} * 2}px;
        background:{vb:stylevar navbar_background};
        padding:{vb:stylevar navbar_padding};
        color:{vb:stylevar navbar_color};
        font:{vb:stylevar navbar_font};
 
        -moz-border-radius-bottom{vb:stylevar left}:{vb:stylevar border_radius};
        -moz-border-radius-bottom{vb:stylevar right}:{vb:stylevar border_radius};
        -webkit-border-bottom-{vb:stylevar left}-radius:{vb:stylevar border_radius};
        -webkit-border-bottom-{vb:stylevar right}-radius:{vb:stylevar border_radius};
 
 
}

Change padding:{vb:stylevar navbar_padding}; to, padding: 0px;
