qdbus on windows

[Peter Kümmel]

I've fixed qt-copy.
Now it is possible to build qdbus also under Windows:

- download dbus for msvc and mingw from:
http://sourceforge.net/project/showfiles.php?group_id=171968&package_id=196620&release_id=431436

- build Qt for Windows
- checkout svn.kde.org/home/kde/trunk/qt-copy/tools/qdbus/
- replace with this qdbus folder the original one in the Qt tree
- set DBUSDIR to the dbus folder
- call qmake -recursive in tools/qdbus
- build
