Properties are already available thanks to QObject: no need to
export them again. Dropping the toString method allows to remove
the plasma-backportglobal.h file for which Krazy had many complains.
The idea is to extend the wrapper to have it wrapping even more
functions provided by Workspace. Of course it would be possible to
just add the properties to Workspace itself and export this. But I
think complete Workspace is just too powerful to fully expose to
scripts. So a small wrapper around the parts which are usefull for
scripts might make more sense.
This breaks now also the API for Workspace and again it is already
more powerful with less code than before.
Unlike stated at several places in the code it is not difficult to
setup the connections to all Clients.
It would have been nice if the failed attempts to connect the Clients
would not have made it into the code as emitted signals which are
nowhere used. Not to mention that like in all places the signals to
inform that a state changed were emitted before the state changed was
performed.
Thanks to Nuno for providing the QML based scrollbar. Obviously
this does not improve the consistency with other widget styles, so
a proper solution is still required.
BUG: 291612
In some unfortunate situations it is possible that a window is deleted
before it is marked ready_for_painting=true. The last point is
especially troublesome for effects that reference the deleted window.
Many thanks to Elias Probst for all the testing.

This includes the delegates, the layout configuration for the delegates
and the custom view for the TabBox.
This can now finally be done as desktop tabbox is based on QML, too.
Buttons are exported as a global "options" in the factory.
Additionally the theme's buttons are also exported. The thme decided
based on the custom button positions property which one to use.
In the kcm the button options are also exported.
Each decoration gets a graphicsview and scene instead and a declarative
item is created for each decoration.
There's probably still room for improvments. E.g. never render the
scene onto the widget but directly into the textures?
