typo errors in the essay on website + translations

[John Mandereau]

Hi the webmasters,
here is a small patch that fixes typo/navigation errors in the essay,
with a ChangeLog entry.

It may be also good to create
site/about/automated-engraving/menu-entries.py containing the line:

[]

to avoid unuseful links "site/about/atomated-engraving" in the menu.

I can tell you that we have nearly finished the french site translation.
What about site/documentation.html? It is marked "4. not to be
translated" in TRANSLATION, but it will certainly be useful it is
translated when the docs are translated - are there plans to translate
the docs? (if the French translators will be soon unemployed :-))) )

Regards
