Introduce compact version of debugger response

If 'compactFormat' argument is passed in the request the response won't include referenced mirrors in the refs section instead each protocol reference object will contain some details necessary for displaying the referenced object in the graphical debugger when the object is not expanded. That allows to request full information lazily when the object is expanded.

How about using the property name 'text', and yust using toText for all types.
With this approach a long string will still cause a large response.

Done for strings. We cannot afford this for all types because some mirrors have
toText returning already beutified values and we want to have control over the
formatting in the UI.
