[LogiLogi-list] Copyright to foundation & contributors file

I changed the copyright-notices in the files to refer to the LogiLogi
Foundation now as the copyright-holder. Also I removed my name from
the model-files I created. Instead of the adding of names to source-
files we will be giving credits to those who contributed to Manta in
the CONTRIBUTORS file in /doc. When Manta goes live we might also show
this list online, in a Logi-page.

greetings,

Wybo
