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
'1,50 { /INdT/ !{ s/(^[ \t:#*]*)([a-z ]*)(Copyright.*Nokia.*)/

We will need to make some modifications to QTestLib to process
QML unit tests.  Once we know what modifications we need, we can
copy them back into the real QTestLib.
