Fix silent table th inheriting background/font-weight from .lbs-table th

Silent tables have both lbs-table and lbs-table-silent classes, so
.lbs-table th { background; font-weight: 600 } was leaking into <th>
cells of silent tables. Add background: none and font-weight: normal
to .lbs-table-silent th,td in all CSS files (style.css + 4 themes).
