MRTG reference page structure malformed

[Daniel-Beardsmore]

https://oss.oetiker.ch/mrtg/doc/mrtg-reference.en.html has some odd problems (and has done for years).

The <title> element is completely borked.

Most if not all the headings are missing their id properties, so the table of contents links do not go anywhere.

The page begins with a huge block of giant grey boxes (NAME, OVERVIEW, SYNTAX etc), none of which actually does anything.

Also the page now ends:

Around line 547:

'=item' outside of any '=over'
