add tempest to the list of documentation

appologies for the white space changes, but my editor purges all
trailing spaces on save, which these files were full of.

reindent for consistency

reindent the javascript and html for consistency based on emacs
multi-mode.

Feel free to ignore if this isn't desired, it just causes me mental
pain to work with html files that aren't indented consistently.

Validate presence of xml:id in section

In tools/validate.py, check for xml:id attributes.

While testing this, found a file that contained missing xml:id, that
was corrected.

See bug #1181659
