Implement tbl(7) lines in -T html output,

as far as they are on the edges of table cells
rather than going through the middle of cells:

* the box, doublebox, and allbox options;
* the | and || layout modifiers;
* and the _ and = data lines;
- but not yet _ and = in individual layout and data cells.
