Use our preferred license text (no more "voices in his head"). While here,
also move to a 2-clause license. From n_hibma@:

"The 3rd clause was originally there for a reason, but I guess that it is
safe to assume that no one can assume endorsement by me or anyone else
without prior consent on anything really, so we might as well remove that
clause."
