Generic Copyright

This commit mirrors varnishcache/homepage@0f25620

as of today, each page redendered from the sphinx source contains the line

	© Copyright 2010-2014, Varnish Software AS.

While this is true for some of the content, it is not for all of it and because
we, several people from UPLEX, intend to contribute significant amounts of
documentation in the near future, we would like to change this into something
more generic, without the need to state specific copyright and authorship on
each page.
