Replace old debugger tooltip by a new ToolTipManager which has a list of AbstractDebuggerToolTipWidget with the functionality to 'acquire' an engine (display its data) and 'release' it (store engine data and display them as 'previous') and serialization to XML session data. DebuggerTreeViewToolTipWidget implements AbstractDebuggerToolTipWidget for tree model acting as a filter on watch models. Rubber-stamped-by: hjk
