glossary: stop generating automatically

The sort_glossary.pl script sorts the glossary, checks for duplicates,
and automatically adds cross-references.

But it's not so hard to do all that by hand, and sometimes the automatic
cross-references are a little wrong; so let's run the script one last
time and check in its output.

Note: to make the output fit better into the user manual I also deleted
the acknowledgements at the end, which was maybe a little rude; feel
free to object and I can find a different solution.
