Monty Taylor 1c07d4ba1a Remove All Rights Reserved
The phrase is no longer needed as of August 23, 2000 with Nicaragua's
joining of the Berne Convention.

Additionally, in at least one instance,
elements/cache-url/bin/cache-url, its existence in the file between
Copyright lines is just weird and feels misleading, even though it is
not.

Remove all of the lines, because sanity.
