Made some changes when creating index.sgml from index.html.
* Changed element names to lower-case.
* Reindented.
* Quoted all attribute values.
* Added elements that are a good idea, but not strictly required (<tbody>)
* Reordered the two main columns. A new row has been added at the top,
and the second column (as it appears in a graphical browser) is in
this row. The left hand side bar is in the second row. Text browsers
should then display the main text first, with the quick links
afterwards. The display on graphical browsers should be almost identical
to how it was before.
Caveat: This forces the first line within the sidebar down by one.
* Removed <b>...</b> from the headings.
* Use &base; in many of the "href"s, instead of ".".
* <font size="4"> --> <big>
* <font size="2"> --> <small>
