[Live-demo] presentation update

[Barry Rowlingson]

I've updated the list of credits in the presentation to all the people
listed as contributors and translators.

However the script has some "especially mention" people:

Cameron Shorter, Hamish Bowman Alex Mandel and Angelos Tzotsos

and some sponsor special mentions:

 LISAsoft, the Information Centre for the Environment at the
University of California, Davis

Anyone else need special mention? Are the sponsors still sponsoring?
