Updated Qt bindings

[Harald Fernengel]

Hi,

after some talks with the KDE people and the original maintainers of the Qt 
D-BUS bindings, we decided to replace the existing ones with the ones from 
KDE's svn server. This allows Qt/only projects to use them without checking 
out KDE stuff (or understanding the KDE build system ;)).

The new bindings work with Qt 4 and link only to Qt Core (no more GUI 
dependency). The Qt 3 bindings will continue to live in KDE's svn, because no 
one wants to fix them up into a releasable state that does more than receive 
HAL events.

Feedback welcome :)

Harald
