Replaced Nokia copyrights with correct Digia copyrights.
Text in front of copyright is now retained:
** File is part of Foo, Copyright Nokia... ->
** File is part of Foo, Copyright Digia...
Replaced Nokia contact details with Digia's.
Removing "All Rights Reserved" no longer leaves an empty line.

Used the following command:

find . -path '*/3rdparty/*' -prune -o -exec grep -ilI -E
'.*Copyright.*Nokia.*|.*Contact.*Nokia.*' {} \; |
tee >(xargs sed -i -r

Too much house-keeping is needed to run tests from resources,
so start the process of removing support to discourage the
creation of poor test harnesses.

This should help make the user application code and
the example code the same.
