unifying copyright entries (was: [RFC] General terminology change)

[Christian Neumair <chris gnome-de org>]

Another aspect are the copyright entries:
Some developery use
(C) <year> <name> or
Copyright (C) <name> <year>,
some others
<name> (C) <year>
and so on.
What's the "official" (or at least the most used) expression?
Additionally, we should replace the (C) by a copyright character
wherever possible (e.g. UTF-8, ISO-8859-X charsets).

see you,
 Chris
