lok: chart: informing the client about selection handling properties

We hijack the chart CID protocol (CID:/classification/ObjectID) by
inserting information about selection handling properties (draggable,
resizable, rotatable) btw the classification section and the ObjectID
section.
This new section has the form: /Draggable=?:Resizable=?:Rotatable=?
where in place of '?' there is 0 or 1.
The hijacking occurs at the ChartController.getSelection method which
is available through the XSelectionSupplier interface.
