changes to copyright messages

[Fergus Henderson]

Regarding the following change:

--------------------
Update the copyright messages so that (a) they contain the correct years
and (b) they say "Copyright (C) ... _The_ University of Melbourne".
--------------------

I won't post a diff, since it is very long, very boring, and I've
reviewed it myself already.  Instead, for the record, I'll post the
scripts I used.

--- fix_the.sed ---
/Copyright/s/University of Melbourne/The University of Melbourne/
/Copyright/s/The The University of Melbourne/The University of Melbourne/
