Replaced Nokia copyrights and contact details

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.*' {} \; | tee >(xargs sed -i -r
'1,50 { /INdT|copy[a-z]*[ ]*=/ !{ s/(^[ \t:#*]*)([a-z ]*)
(Copyright.*Nokia.*)/
\1\2Copyright \(C\) 2013 Digia Plc and\/or its subsidiary\(-ies\)\./I
 }}') >(xargs sed -i -r '1,50 s/(^[ \t:#*]*)(.*info@qt\.nokia\.com.*
|.*INSERT EMAIL ADDRESS.*|.*qt-info@nokia\.com.*
|.*qt-label1@nokia\.com.*|.*http:\/\/qt\.nokia\.com\/contact.*
|.*qt-sales@nokia\.com.*|.*http:\/\/www\.qt-project\.org\/.*)/
\1Contact: http:\/\/www\.qt-project\.org\/legal/I')
>(xargs sed -i -r '1,50{/(^[ \t:#*]*)(all rights reserved.*)/Id}')

Command now finds command details that point to qt-project.org and
changes them to qt-project.org/legal
Also no longer wrongly replaces code snippet "copyright = ..". Need to
fix these case-by-case later.
