[lm-sensors] Updated list of contributors

[Jean Delvare]

Hi all,

I just updated the "Authors and Contributors" page on our web site. It
now reflects the current team and roles better, or so I hope. I also
reformatted the entries in a more convenient way (less space) and added
some links.

Anyone is free to edit their own entry and/or add a link from their name
to their home page. Or, for those without a write access to the wiki
and not interested in said access, just tell me what change you want
and I'll do it.
