lok: chart: constrained dragging of pie segments

The extra information for the graphic selection is now formatted
according to JSON syntax so that is easier to parse.

Information for allowing the client to performa constrained dragging
of a pie segment is appended when needed to the graphic selection
message.

A polygon approximation of the pie segment in svg format is attached
too to the graphic selection message.

Core now is able to handle a specific msg from the client with data
about the new pie segment offset computed by the client on drag end.
This information is dispatched by the chart controller to a specific
method: executeDispatch_LOKPieSegmentDragging.
