0031362: Inspectors - MessageView plugin for message alerts

- append new MessageView plugin to display content of Message_Report; - correct DumpJson of TDataStd array attributes to print Lower/Upper values; - correct remove level of Message_Report to store stop time during removing all levels; - append DumpJson for TFunction, TPrsStd attributes; - correct DumpJson of XCAFDoc tools due to simplify performance of it; - move AttributeInfo functionality from XDEDRAW into a static public method of XCAFDoc to call it outside; - remove obsolete pane classes in DFBrowser plugin, now we may use DumpJSon panel to visualize this content of attributes; - add new property panel in DFBrowser (synchronized with the same in other plugins); - add button to switch ON DumpJson in DFBrowser(OFF by default, for better performance), also there is a context menu item in tree view; - rename in DFBrowser "Property Panel" into "Property Panel (custom)"; - implement ViewControl_ColorSeletor and setting color in TreeModel_ItemProperties. Use only for light in VInspector now; - implement setting false for all created AIS_Shape presentation to don't modify source TopoDS_Shape; - remove not use VInspector_CallBack. It's possible using Message_Report/MessageView to track commands way; - remove History panel in VInspector as not used, MessageView will be better solution for this; - implement item and actions in VInspector for setting Lights in the view.
